Stretch Goal 2 Reached - Raspberry Pi Users Get Their Board!
WOW! 5 Days to go and we've reached our second stretch target! Thanks again Kickstarters for your continuing support.
As promised, this landmark enables us to create a add-on board for the Raspberry Pi to hold the OLED breakboard. A 3D representation of the board design is shown below.
This board connects the SPI interface from the breakout to the Pi and the other control signals are routed to Pi GPIO pins. All you need to do is just plug in or solder in your OLED breakout board, plug into your Pi and away you go.
We've also added a 5 way (4 direction plus select) switch to allow you to control menus or anything else on the display. The switch is routed to five of the Pi GPIO pins.
UPDATE: We've also now added a micro-sd card socket under the board to make it eve easier to access your images etc.
We've added some new rewards for those of you who would like to add an PiOLED board. If you would like both the PiOLED board and the Arduino Shield then please choose either the "I want more fully easy" or "I want more fully easy as Pi" options and we will ask your which combination of boards you would like when we contact you at the end of the campaign.
We've had loads of positive feedback and interest that we've decided to add some stretch goals.
If we can reach the second goal, we will add some new rewards that both new and existing pledges can take advantage of.
ILSoft Ltd is an electronics and software company which specialise in bespoke projects. One of the items we've often wanted to use in our gadgets is some kind of display and up until now we've used 7-segment displays, text LCD displays and graphics touch LCD screens.
On our latest designs we wanted to use a colour OLED display due to its small size, high pixel density, clarity of display even in daylight and no need for a back-light – but have you tried to get hold of one of these displays with a simple interface and at an affordable price?
Step forward the ILSoft Colour OLED Breakout Board!
This breakout board provides a simple way to add a full colour OLED display to your project or product using a simple SPI interface. It measures just 40mm x 50mm and houses a 1.5” 128 x 128 pixel OLED display. We've added regulator, buffer and voltage step-up circuitry so that you can connect the board directly to either 5 volt or 3.3v circuits without the need for any additional buffering or voltage changes. The connections are via a 6 pin 0.1” spaced connector so it’s ideal for breadboard connection or into your project board. (Note: This project includes the breakout board complete with the OLED display already attached)
And code as well!
If you've ever looked at the code required to initialise a colour OLED display it can sometimes be a little daunting so, to get you off to a flying start, we've also produced a set of library code for Arduino, Raspberry Pi and PIC. This means you can simply drop the code into your project and be drawing full colour graphics, text and images in minutes. Using the datasheet for the display you can then explore all the functions of the OLED display and expand our routines to create your own functions. The possibilities are endless!
- Board Size: 40mm x 50mm
- OLED Size: 1.5"
- OLED Resolution: 128 x 128 pixels
- Colour: 256,64k or 262k colours
- Interface: SPI (SCK, SDO, CS and Reset)
- Supply Voltage Min: 3.3v
- Supply Voltage Max: 5v
- Logic Level: 3.3v - 5v
Why we need you
We have currently created a prototype board (see pictures) which, as might be expected, resulted in a couple of small ideas of how to improve the design. We want to remove the cut-out and have the OLED ZIF connector on the front of the board to aid mounting and prevent strain on the OLED connecting cable. We’re also going to add a power LED and some mounting holes. As we speak, the second prototype PCB is being manufactured.
At this stage everything looks fantastic but we need your help to attain the final part of the project. This is to be able to create a production run so that the price can become affordable.
With your support we can make the addition of these brilliant colour OLED displays into everyday projects an affordable reality.
Risks and challenges
We have spent a considerable amount of time refining the design, the components used, and the schematics. We've created and tested the first prototypes. One of our biggest challenges is volume. The first driving force on this project was to make colour OLED boards affordable. We have a manufacturer lined up but without a high order volume we won't be able to get the cost low enough to reach our “affordable” goal. We've set our funding goal at what we hope is a realistic target but also at a level that allows us to place a large enough order with the manufacturers.
Another challenge we face is make sure enough people get to know about our project. We know this is a brilliant breakout board which works well, is robust and does exactly what it says. It is a great, low cost way to get a full colour OLED display into your project and is something the hobbyist and professional community needs. However, without your support it won't make it to production and we’ll all be stuck with “old technology” text LCDs!Learn about accountability on Kickstarter
