  • Pin compatible with Arduino uno;
  • Two UPin-27 standard interfaced female heades, and the corresponding pin has connected;
  • Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly;
  • Two Female Heade's each pin interconnects and vertical arrangement on the board which can reduce the overlay height;
  • Onboard analog buttons, extended interface;


  • Electrical specifications
    • MicroUSB power supply;
    • 3.3V regular;
    • Select the 5V or 3.3V power via PWR jumper, default is 3.3V;
    • Onboard power supply (5V、PWR) indicator;
  • Extended pin
    • Onboard reset button;
    • OLED fixed base;
    • Two serial ports, RX0、TX0(Serial) and D2、D3(Serial1);
    • Tw IIC interfaces;
    • Two analogy button interfaces, and connect to A7;
    • Seven analogy buttons. Two buttons on base board and connected to A6. Five button on overlay board and connected to base analogy button interface by DuPont line;
    • Two group sensor interface, can be combined by jumper. The player can make the connection by yoursefl, as follows:
      • PWR,GND,A3 or PWR,GND,A6;
      • PWR,D5,GND or D4,D5,GND。
  • Components
    • base board:with two UPin-27 standard interface;
    • Overlay board: use to fix the five analogy buttons, OLED;


Eagle PCB local download Main components:


It can be used with other Microduino modules, sensor to achieve specific functions.


  • 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.
