      I'm new to hardware hacking, and I'm not sure what a kit is, versus a shield, or how I would use either. Is there anywhere that explains this, or any sort of explanation of what each of the offered extras actually are? Or can you suggest some sort of Beginner's Kit? I want to make sure I have enough to make my initial foray into the land of open source hardware fun, but I don't know want to go buying things willy-nilly. Will the shields be sold separately later?

      It would be useful to have an example of what you'd use each type of shield/board for.

      @Joesph - the Digispark is about 1/10 the size of a Arduino so we'll probably focus our efforts more on equally small shields with similar (or better) functions rather than adapters for larger pricier ones. With a digispark proto shield and some wire and headers one could easily make their own adapter, as they would be very shield specific.

    3. Joseph Chang on September 8, 2012

      Will you be creating adaptors in the future for some basic compatibility with full sized shields?

    4. Erik Kettenburg 6-time creator on September 7, 2012

      @Joseph - the Digispark has far less pins, so generally no - though some of the simpler shields and likely most any I2C shield should work.

    5. Joseph Chang on September 7, 2012

      Is this compatible with current existing Arduino Shields?

    6. Erik Kettenburg 6-time creator on September 7, 2012

      @Tyler - not easily, mostly their for storage, you might be able to do it but it won't work out of the box.
      @Dustin - sorry we're just out of time, but we might make several designs and just give them away when we ship!

      @EriK KettenBurg I'm sorry To bother you but I have a fast question before the kickstarter closes! I'm brand new to Arduino. Say I were to write a lengthy program bigger than the Digispark supported, If i buy an EEPROM shield could I store some code there and run it? or are eeproms strictly for data recording?
      Thank you if you get to this, or anyone else that could help.

      I am *so* excited about this! The only thing I'm planning for certain is a MIDI trigger for my sister--she's a musician, and she's got software that responds to MIDI commands, so she'd like a small button or footpedal she can use to trigger it. I've also experimented with using the analog inputs to modify the commands, so I'll probably also make some sort of MIDI "instrument" which plays different notes, different velocities, etc. (I'm experimenting with an UNO, but I'm only using a couple of pins, so the DigiSpark should be no problem.) And I'll probably leave a couple of boards just as RGB LED controllers, so I can fiddle with the computer programs for them, a little like the "Ambient Orb." But I'm also thinking about using one in a switched-mode power supply to regulate my dad's bicycle generator's output to his headlight LED (hopefully roughly doubling the output current, while halving the voltage--my attempts at simpler circuits for this failed, because I don't have a good theoretical model for the generator's response to circuits; my SPICE software said they'd work with the model I was using, but in practice they did not); one to program PICmicro chips, for the menial tasks that don't deserve a full Arduino (particularly since my new computer doesn't have a parallel port to supply my old PICmicro programmer); and...I don't know what else, but it'll be a blast finding out! It's very exciting stuff. It makes me feel empowered and creative. Thanks so much for this project!

      Any thoughts to making stickers available as extras you can purchase? It'd be fun to have a few extras. Perhaps that could even be the $250k goal; a couple of designs you can choose and purchase from. =)

      @hacktc. If you want a taste of what you can do on hid programing google "irongeek phukd". Close to the bottome of the page he has some code samples as well as a download link for his library and further example sketches.

      @Erik Kettenburg. Excellent. I hope there will be some sample code demonstrating pushing a keyboard button or something simple like that.

    13. Erik Kettenburg 6-time creator on September 6, 2012

      @Peter - it should work with those just fine, no shield needed but it you want to be able to directly plug them into one then maybe the proto shield so you can attach a header and wire it up in the right order.

      @hacktc 1 - no, it can't act as USB host 2- yes!

      hacktc on September 6, 2012

      I assume this must have been asked by now, but I don't really see a way to search old comments. I have two questions -

      1. Can the digispark be used as a USB host controller for something like a very simple Android ADK solution?
      2. Can the digispark be used as a HID compatible device to simulate a keyboard, mouse or joystick?

      I will happily add a few more to my bid if either or both of these is possible. :-)

      Thoughts on using a Digispark with this: or this:
      What if any shield or kit would be useful for using these with a Digispark?

    16. Erik Kettenburg 6-time creator on September 6, 2012

      @Ryan - you can attach one shield per digispark with the included headers - if you want to stack shields on top of each other you need some stackable headers

      So Digispark+RGB - no stackable headers needed
      Digispark+LCD+Infrared - one set needed for the LCD so that it can plug into the Digispark and the Infrared can plug into it.

    17. Sparr Risher on September 6, 2012

      @CK you could easily use a digispark to drive an arbitrary number of these:

    18. Sparr Risher on September 6, 2012

      @CK I do not know of any RGB LED matrices as small as the one I'm using for my red-only shield (20.20mm square). However, if you go with a bigger matrix, then you have a lot more room for components, and it would not be terribly difficult to build a shield that drives it.

    19. Ryan Blackwood on September 6, 2012

      Erik - I notice a lot of people aren;t getting any stackable headers. I was under the impression you needed stackable headers in order to use any shields. Is that not correct?

    20. Erik Kettenburg 6-time creator on September 6, 2012

      CK - you'd be short on pins for doing it directly but there are many i2c chips that might let you do something like that such as:

      Sparr's doesn't do RGB leds so it uses much less pins, but he is using an extra chip as well - checkout our charlieplex shield for a real small version with just red leds.

    21. CK on September 6, 2012

      Does anyone knows whether it is possible to create something like lowcost L8 smartlight that can handle so many RGB LED (in terms of memory or other limitation)?
      Of course I don't expect it to be wireless, but at least we can control what to be displayed. I saw something very similar provided by Sparr Risher at the video link below.

      Hi Erik,

      Myself and a group of friends from our local HackerSpace (20 people in total) have gotten together to back your project all the way from South Africa! We're very excited to be a part of this and can't wait to get our Digisparks.

      Our local postal system is notoriously bad though. We were wondering if we could pay extra for priority international shipping, perhaps with a courier company that has proper tracking and door-to-door delivery? Something like DHL or FedEx, rather than the United States Postal Service which only tracks parcels up to the US Border? Prior experience with other KickStarter Orders (by friends and family) has been rather bad - we have yet to receive any of our physical items. They simply go missing in our local postal system with no accountability or traceability.

      We really want to make sure we get our DigiSparks and Shields! Our order is quite large! Please let us know if we can make an arrangement.
      Thanks for creating an awesome Hack toy! BUILD ALL THE THINGS! :D

      I missed the IR shield pcb from that list it falls between rfm12b and grove

    33. Erik Kettenburg 6-time creator on September 5, 2012

      @Dennis good idea
      In order - most copies to least:

      Breakout version A
      Breakout version B

      Shield PCBs:
      Through hole prototype
      SMT prototype

      I think I got them all.

    34. Sparr Risher on September 5, 2012

      @michael if you like lots of LEDs, wait til you see the shield version of this that I'm making:…

    35. Dennis Watkins on September 5, 2012

      @erik - anyway we can get a list of the most popular shields? For those of us who can't decide. maybe we can piggy back on some of the people who do know. If I see most of the people buying x shield, i might pick one up just in case I want to try to figure it out later.

    36. Michael Meissner on September 5, 2012

      FWIW, I'm currently buying: three digisparks at $28 (the idea being to have multiple, so that I can work on multiple things at a time).

      2 Shield PCBs at $1.25/each. This is primarily to allow for making small things without using a breadboard. Now, that digispark has redesigned the board so it can fit directly into a breadboard, I don't feel the need as strongly.

      No surface mount shield PCBs, since at present I'm still a solder newbie, though I just need to actually take the time to learn the skill, since I will need it with the digispark.
      1 RGB kit at $1 each. Its cheap, and as the blink(1) project shows, you can use the multiple colors to indicate status.

      Breakout shields both A and B at $2.50 each. This is useful to mount sensors and servos that take 3 pins, and most use a 3 pin connector. Unfortunately there are some things that have the 5v pin in the middle (shield A) and some that have the data pin in the middle (shield B), so I'm getting both shields to be sure.

      Infrared shield kit at $3.50. This will allow you to make a digispark that can simulate other IR devices like turning a TV set on. I've had bad luck trying to make my UNO operate as an IR receiver, and I think I burned out my IR LED, so I wanted a kit with all of the parts, etc. I wish the shield had a mounting hole for an IR transmitter LED so you could do a remote control and receiving. Yes, you can plug in the light + resistor into an available pin, but it would have been useful to have it in the shield.

      No grove shield kit at $2.00. I don't have grove sensors, so I didn't see the need.

      No motor shield kit at $6.50. While I've wanted to get into motors, I didn't feel the need as much for the digispark. I have a motor shield for my UNO, and a lot of what I want to use motors on, I probably will need more pins, and it would be harder on a digispark.

      No MOSFET sheild kit for $3.50. At present, I'm not playing in the the space of having to deal with higher voltages than 5v, so I don't see the need for me.

      1 Charlieplex LED shield kit for $5.00. This is just for fun, to have the digispark do patterns.

      No LCD I2C Shield Kits for $15. I'm kind of on the fence on this one. I have a 16x2 shield for my UNO, and the few times I've used it, the 16 columns is a challenge to write dialogue in. I have 20x4 I2C shields in my ebay watch list that I may buy some day. Also at $55, I'm close to the limit I would feel comfortable spending right now given some of the other things I've been buying.

      No relay shield for $6.00. I already have a relay that I bought for other projects, and I don't need another one. But if you wanted to control the power to A/C devices it would be useful.

      No EEPROM shield kit for $4.00. At the moment, I'm not in need of storing a lot of data on the Arduino, so I don't feel the need.

      No port expander shield kit for $6.00. At the moment, I don't feel the need, since I do have the UNO for things that take a few more ports.

      No boost shield kit for $9.00. At the moment, I've pretty much settled on 5v batteries meant for charging USB devices, so I don't feel the need for smaller voltage batteries.

      One case kit for $10. This would allow putting the digispark in areas where it needs protection from things that move around.

      No stackable headers for $1.50. I haven't decided yet on whether I need these. At present, I don't feel the need for stacking shields.

    37. Luis Fraguada on September 5, 2012

      Hey Matthew... good question! This will be pretty personal for each person, but perhaps I can share the reasoning behind my extras. I think all of the extras are cool, but some are really cool for the things I am working on and wanting to work on. For example, I feel the boost shield is pretty useful as it allows one to work with lower power sources (2v - 4.5v). Good for hooking this up to a couple of AA, 3.7v LiPos, etc. I am also picking up a protoshield or two as the general pin breakouts. I like the EEPROM shield kit and the I2C port expander as it broadens the capabilities of the platform which is short on memory and pins. The RGB kit is well, $1! Also, I am going to test out the RFM12b as I already use it with the Jeenodes around here. Since it is more experimental, it might be a good idea to hold off on that one till some people have tested things...

    38. Matthew Peck on September 5, 2012

      Can someone recommend one or a few extras that we really shouldn't miss out on as backers? Like, a couple shields that I'll be kicking myself later if I don't get them now. And not necessarily just shields. Basically, if I'm backing at the $28 level, what would I want to add without going over $40 or $50?

    39. Matthew Peck on September 5, 2012

      For 250K, how about a minimal-sized Standard-A female to Mini-B male USB adapter? Something that adds as little as possible to the form factor while allowing the DigiSpark to be plugged into, say, certain smartphones or other Mini-B devices?

    40. Erik Kettenburg 6-time creator on September 5, 2012

      @david an IR emitter can easily be added to the IR shield or proto shield allowing you to send and receive IR codes - like a supper tv-b-gone - you could program it so if it detected the off signal from one remote it shut off everything else or something like that.

      @CK - that sounds like a great idea - we'll do it once they ship but not as a goal, just because - still looking for 250k ideas!

    41. Sparr Risher on September 4, 2012

      @david the IR shield is an IR receiver. an IR transmitter is just an LED, not nearly so complex. the tv-b-gone doesn't include a bootloader, and they cram all the memory with different TV codes, so you'd have to eliminate some codes to fit it on a digispark if you don't want to erase the bootloader first.

    42. david moloney on September 4, 2012


      this cool kickstarter project has an SPI interface for an arduino board

      digispark looks like a great fit for it :)

    43. CK on September 4, 2012

      I have an idea on 250k goal. How about organizing a contest for the most creative implementation using digispark? This will encourage more backers to submit their idea (maybe submit via video), the most voted idea wins! It will be great if Erik can sponsor first, second and third prize :)
      How is that sound?

    44. Erik Kettenburg 6-time creator on September 4, 2012

      CK - yes, yes, and most likely yes - the last one we haven't tested but they are soldered at well over 250 degrees Celsius so I don't imagine the heat of a car will cause any trouble

    45. CK on September 4, 2012

      So basically will this work if I plug it (with sensor or LED) into a normal wall power outlet with USB port?

      If I use it in the car (USB port through car 12V socket), can it survive the heat if I park it under the sunlight?

    46. Jay Keeley on September 3, 2012

      has anyone created eagle files for the digispark? they would be quite useful to begin developing ideas :-)

    47. Tan Jit Ren on September 3, 2012

      just backed this awesome project! would like to use it in my future projects!
