About this project
MICRODUINO FEATURED IN...
A small sized board that packs a great punch!
The Microduino series is a 100% Arduino compatible open source hardware, compatible with Arduino IDE development environment and existing Arduino sketches.
MICRODUINO IS SMALL
Microduino is small. Its size is about a quarter (25.40mm X 27.94mm / 1.0inch X 1.1inch), much smaller than the original Arduino board.
MICRODUINO IS STACKABLE
All Microduino boards adopt a uniform U-shape 27-pin standard pin-out (UPin-27). Thus Microduino series can be easily stacked together through the UPin-27, and all modules are delivered ready to stack.
Microduino configures the pinout usage table well so as to avoid any pin usage conflict between different extension modules.
MICRODUINO IS OPENSOURCE
We've benefitted from the open source community, and we're dedicated to giving back. The Microduino is a totally open source hardware product. you can get all of our hardware design files (schematic, board design) and firmware from Microduino WIKI http://wiki.Microduino.cc
MICRODUINO IS CHEAP
Once you upload an Arduino compatible program onto the Microduino, you don't need Microduino-FT232R anymore. You can just put Microduino-Core into your system. One -FT232R module can be reused in different applications.
Also there are various Microduino pin-out compatible (UPin-27) extension modules available with low price (check details below), which decreases prototyping and production cost.
With Microduino, it's easy and low-cost for you to build your owner applications, realize your bright ideas and conduct low volume production.
You can reach us through Facebook, Google+, Twitter and Wiki for more Information.
MAKE COOL THINGS WITH MICRODUINOS
With its tiny shape, the Microduino series dramatically decreases the size and cost of prototyping, while also remarkably improving usability and flexibility of Arduino-compatible boards, as well as user experience.
Microduinos are smart, small and stackable. With various Microduino extension modules, designers can easily make many different kinds of applications.
Here are some existing Microduino designs which are already applied by designers.
Microduino-Gate for Web of things
A WOT network gate is a hub for distributed sensor nodes. Different kinds of sensor nodes collect environment information, like temperature, humidity, pressure and so on. All such kind of information will transfer to network gate. Microduino hub processes all information and puts it to internet as you wish.
Microduino-Wireless Gate for Web of things
If you want to make the WOT network wireless, you just need to stack a Microduino-nRF24 to your system. If adding extra Microduino-SD module, you would be able to record environment information offline.
Microduino-LM4863 is a D-Class amplifier, popular and high quality digital amplifier. Integrate into your application to build a cool design!
A GPS logger needs 5 modules: Microduino-Core+ + Microduino-[BT] + Microduino-SD + Microduino-OLED + Microduino-GPS. The black Microduino-OLED Breakout board is optional to make your design cool, because all Microduino pinout and bolt holes are standard 2.54mm/0.1inch pitch, designer can build their own application on a hole board.
To smart your room, use your cell phone to control water machine, curtain, or switch lamp when you are not physically in your room. An open source software is also provided to help you build your own smart room system.
Smart your garden? Want to conserve water and energy, to switch off the air-conditioner, ventilation fan, and turn off the tap remotely? It's easy to realize with Micrdouinos.
You can find more cool applications from internet:
- Connecting Pebble with Microduino
- a Bicycle computer with Microduino
These are just a few of the projects that Microduino community members have built in past one year. We'll be sharing these ideas, and any others we dream up in the future. We hope you'll do the same!
Stack them and play, here we go!
THE IDEA BEHIND MICRODUINO
The Idea behind Microduino is dividing Arduino-Uno circuit into 2 functional parts: Microduino-Core and Microduino-FT232R. The -Core part is an Arduino minimum system board, and -FT232R is for signal communication between PC and -Core for sketches uploading and debugging.
Microduino is structured as a uniform U-Shaped 27 pinout (UPin-27). All Microduino boards adopt the UPin-27. Hence every Microduino can be easily stacked together.
This idea makes Microduino very flexible, smart, cheap, and compatible with Arduino Ecosystem: Microduino-Core + Microduino-FT232R = Arduino Uno.
MICRODUINO CORE MODULES
We defined Microduino modules as "Core Modules" and "Extension Modules", a "Core Module" means Ardunio minimum system board and USB2TTL boards. There are currently 3 "Core Modules" in Microduino series.
Microduino-Core is core board of Microduino series. Its main chip is ATmega328P, and it's completely compatible with Arduino Uno, the same hardware architecture as the Uno. You can just select the board type as "Arduino Uno" in the Arduino-IDE, when uploading programs/sketches onto the Microduino-Core.
(check details in wiki)
Microduino-Core+ is a performance edition Microduino series, another core board of Microduino series. Its main chip is ATmega644PA and its performance matches that of the Arduino Mega2560. Microduino-Core+ provides 2 hardware serial ports and 10 more digital I/O.
To use Microduino-Core+ in Arduino IDE environment, you must patch the Microduino Arduino IDE hardware package. You can find a tutorial on the Microduino wiki page to guide you step by step.

Difference between -Core and -Core+
Both Microduino-Core and Microduino-Core+ use UPin-27 -- the standard pinout of Microduino series. The main difference between them is the core chip: Microduino-Core module uses ATmega328P or ATmega168PA which is the same as in Arduino Uno. However the Microduino-Core+ module uses ATmega644PA or ATmega1284P, and its performance matches that of the Arduino Mega2560.
Designers can select proper modules according to their application requirements in terms of function, performance and power.
In Kickstarter, Microduino-Core (328P/5V/16M) and Microduino-Core+ (644PA/5V/16M) are provided. Other version will be supplied in Microduino webstore around Dec/2013.
Microduino-FT232R is a USB2TTL module for connecting PC with the Microduino and uploading programs/ sketches onto the Core/Core+.
(check details in wiki)
Microduino-Core + Microduino-FT232R == Arduino-Uno
Microduino-Core+ + Microduino-FT232R =~ Arduino Mega2560
Simply stack the boards together, start your Microduino Journey!
MICRODUINO EXTENSION MODULES
Micrduino "Extension Module" means a board featuring different functional applications.
Microduino line already features a variety of modules, covering network, wireless communication, BLE, SD storage, GPS, Wifi, motor/stepper driver, OLED display, battery management, and more modules are under testing. With the extension modules, designers can easily achieve different application purposes.
Microduino-ENC (Microduino-Enc28J60 + Microduino-RJ45)
Microduino-ENC enables ethernet communication between core module and internet.
Microduino-nRF24 is used for wireless communication in 2.4GHz band.
Microduino-SD is a Micro SD card jack, using SPI communication protocol.
Microduino-[BT] is Microduino BT Shield. There are two versions: BT2.1 and BT4.0, we will supply -[BT] 4.0 version in Kickstarter campaign by default, if you want -[BT] 2.1 version, please comment it during survey when we accomplish this campaign.
Microduino-10DOF sensor module integrates three vector chips: MPU6050 + HMC5883L + BMP085. They use I2C protocolUPin-27: Microduino standard interface.
Microduino-BM is a Li-ion battery management module. It has full functions of charge, discharge, voltage detect and LED indicator. It supports 3.7->5.V and 3.7V->3.3V.
Microduino-OLED is a 0.96' 12864 display module, and it uses SSD1306 driver with I2C protocol. It's supplied by 3.3V voltage.
All above boards are already mass tested in Microduino community and are ready for production. Many designers have already used them to build their own applications.
OTHER MICRODUINOS (PASSED INTERNAL TESTING)
There are also some other Microduino extension boards already tested in-house, but not mass tested in Microduino community yet.
Microduino-LM4863 -- a D-Class Amplifier
Microduino-RTC -- a real timer modules
Microduino-CC3000/WG1300 -- a WiFi module, solution from Jorjin Technology (very popular now, huh?)
Microduino-NEO6M -- a GPS Module
Microduino-A3906 -- a Motor/Stepper driver module
Microduino-A4982 -- a high performance Motor/Stepper driver module
We plan to finish mass testing of the above boards (-LM4863, -CC3000, -RTC, -NEO6M, -A3906, -A4982) around September 2013.
MICRODUINO SHIELDS AND ACCESSORIES
Stacking boards together is a good idea. However, when your system becomes complex, you don't want to stack too many Microduino modules with increased height. In order to decrease stack height without sacrificing functions and to make design elegant, Microduino shield boards are provided.
Microduino-Solo (Test Boards)
Microduino-Solo is a test board for Microduino.
All Microduino pins are brought out to the peripheral of Microduino-Solo. It's easy for designer to tune pins and debug circuit connection. A 5.0V to 3.3V DC-DC regulator is embedded to provide two voltage levels. A Jumper can be used to switch the supply power.
A Duo-board connects two UPin-27 pinout together. We designed two types of Duo boards, which respectively connect Microduinos in two directions -- vertical and horizontal. They are named as Microduino-VDuo (1x2 mode) and Microduino-HDuo (2x1 mode).
Microduino-VDuo connects two Microduino boards in vertical direction.
Microduino-HDuo connects two Microduino boards in horizontal direction.
Microduino-Uno -- Arduino pinout shield
An Arduino pinout shield is also provided in Microduino series to match Arduino pinout. It's an interface switch board between Microduino and Arduino.
Microduino-Uno shield is designed for multiple purposes:
1. If you are new to Microduino, or know little about Arduino, please use this board to start your Microduino adventure. By just stacking Microduino-Core and Microduino-FT232R on this shield, you can get equivalent Arduino-Uno and then leverage world-wide Arduino community technical resource to learn Microduino.
2. Well, the idea of Microduino is really nice and you just want to try it out. If you already have many Arduino extension shields, it's not efficient to get rid of all of them. No problem, try Microduino-Uno Shield, with which you can connect Microduino and Arduino together.
3. The last scenario - you already have an Arduino board. Obviously, Microduino extension modules are more economic than other Arduino extension boards. By just stacking Microduino-Uno shield on to your existing Arduino Board, you can easily stack Microduino extension modules, and begin to use the power of them.
Microduino Fritzing library
For better experiencing Microduino, Microduino team designed a series Fritzing library, you can share your idea with Microduino in a nice way.
Microduino Fritzing library can be freely downloaded from Microduino Wiki web.

Joanna WEI, the executive director of Beijing MakerSpace, is helping with Microduino social media campaigns. The goal is to encourage social innovation and develop the open-source hardware ecosystem by building a physical and online community in China.
MICRODUINO PLEDGE PLAN
Microduino modules have been designed, developed, prototyped and tested. Right now, we only share our small adorable boards within Microduino community, in which there are around 700 geeks from China, Europe and US. We organize the community through http://www.weibo.com/Microduino (China Twitter) and QQ discussion group "123972320" (China IM).
Although hardware product costs more money, with your support, we can start mass production. So we can share the tiny powerful boards with more designers around the world. Once we successfully achieve pledge target, we will start shipping modules that you back.
We configured project pledge items according to different application purposes, and packed them into different kits. (check overall package table here)
Most Microduino modules are ready for manufacturing, the factory is only waiting for the final quantity; that will be available at the end of this campaign, so the production will start immediately after this campaign is over, 10th of October.
We've organized the whole process to be completed in only 35 days.
During the first 10 days (in best case, it will only take 7 days), the PCB manufacturer will create the boards and execute the electronic tests. At the same time, the sourcing office will order and collect all the components.
Starting from the 20th of October the manufacturing plant will run the SMT assembling, the manual soldering of the components that are not surface mounted, and the finshing of the boards. This factory has produced Arduino compatible boards before, so they have experience and knowledge to perform these tasks properly.
At the same time, we will start to prepare all the materials for shipping.
15 days after the end of the campaign the Microduino boards will be ready for quality control and testing. The boards need to be programmed with a special test software that we've designed, tested and then programmed again to be ready to work with your computer.
Starting from the 11th of November we will be able to ship your rewards, but we want to keep a window open for possible delays, so we plan to complete the whole project by the December in the worst case.
In case the interest we receive is higher than what we expect (let's say many times the goal) the production time will not be much longer and we can upgrade the output capacity up to 500 orders a day.

Risks and challenges
A project of Hardware product is always challenging.
Fortunately, our product development risk is minimum. Most Microduino series boards have been designed, developed, prototyped and tested by Microduino community and used for many applications. The design and the production's specifications are ready. As soon as the project receives 100% of the funding, we will start production, even before the end of the campaign.
We also plan to test the remaining 5 modules to ensure the stability and performance from production. They have already passed our internal testing. If everything goes well with production testing, we will deliver the kits to you by the end of October. Otherwise, we will refine the design and start our product shipment in November 2013; it's still within our schedule.
The second challenge is from manufacturing. We have to make sure our mass production can efficiently manufactures reliable modules. During the past one year, we have already established close relationship with our manufacturing partner in Shenzhen, China, who has been manufacturing high quality modules for us. In addition, we have another manufacturer in Beijing, China as a backup which one of our team members has been using for years. They both have already been proven highly capable, therefore manufacturing risk is minimized. Nonetheless, there are still risks associated with producing the Microduino. We are working hard to mitigate those risks and plan to be transparent throughout the process.
The third risk is from physical delivery. We plan to work with proven companies to help ensure that your rewards arrive on time in perfect condition. In case of unforeseen circumstances, we will try our best to overcome any difficulties.Learn about accountability on Kickstarter
