  • Pin compatible with Arduino uno;;
  • 2.54 pitch board is the base for Microduino module, the same name pin are connected to each other on board, easy to debug.
  • Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly;
  • 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;
    • Sensor interface can be combined by jumper, The player can make the connection by yoursefl, as follows:
      • PWR, A3, GND, PWR or PWR, A3, GND, GND or PWR, D6, GND, PWR or PWR, D6, GND,GND.


Eagle PCB local downlaod 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-S1, test program Microduino-Cube-S1-Text.zip
  • Prepared hardware:Microduino FT232R, Microduino Core, Microduino-Cube-S1, 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 download, OLED displays "No button is pressed ",
    • Press the left button, OLED displays "Press the left button" which means the left button was pressed;
    • Press the right button, OLED displays "Press the rignt button" which means the right button was pressed;
    • If no button was pressed, OLED displays "No button is pressed ", the same state with initial state.
