Features
- Pin compatible with Arduino uno;
- Two UPin-27 standard interface bases connected with the corresponding pins；
- Uniformed Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors meeting Microduino interface standard;
- Two bases are arranged longitudinally with pins interconnected on the board, making it possible to reduce the stacking height;
- Onboard analog button and sensor interface;
Specifications
- Electrical specification
- MicroUSB power supply；
- 3.3V constant voltage；
- Select the 5V or 3.3V power via PWR jumper.(The default voltage is 3.3V)；
- Onboard power supply indicator(5V and PWR)；
- Extension
- Onboard reset button；
- Fixed OLED base；
- Two serial ports including (RX0,TX0)and (D2,D3)；
- Two IIC interfaces；
- Two analog button interfaces connected to A7；
- Seven analog buttons with two on the board connected to A6 and five on the stacking board connected to the interface of the base with Dupont lines；
- Below are two groups of sensor interfaces which can be selected and combined through jumpers. Users can choose different jumper connection as they like:
- PWR，GND，A3 or PWR，GND，A6；
- PWR，D5，GND or D4，D5，GND。
- Components
- Base board：The board with two UPIN-27 standard interfaces;
- Overlay board: The fixed board of five analog buttons and an OLED;

Development
It can be used with other Microduino modules, sensor to achieve specific functions.
Application
- You can download the test example, and combine OLED to test two analogy of Microduino-Cube-V1, test program Microduino-Cube-V1-Text.zip
- Prepared hardware：Microduino FT232R, Microduino Core, Microduino-Cube-V1, Microduino OLED；
- Prepared software：Microduino example program (Arduino part), Arduino IDE(1.0 release and upper)；
- Open the example program in IDE, select the board "Microduino Core (Atmega328P@16M,5V)", download directly;
- After the download is completed, OLED displays similar patterns with analogy keyboard. Press each button on floor and roof analog buttons can simulate the corresponding position's button.
