    Elecfreaks Microbit Breakout Board

    Manufacturer: Elecfreaks
    Micro:bit breakout board is a kind of breakout board for micro:bit. It can lead out GPIO port, serial port, IIC port, and SPI port on the micro:bit board. The biggest feature of Octopus:bit is that it can switch electric levels for some GPIO ports, which makes micro:bit available to be adapted to 5V sensors.

    FEATURES
  • Input voltage: 3.3V(powered by the edge connector of micro:bit)
  • Extend all the GPIO ports(P0~P16, P19~P20).
  • Beneath each I/O port, there are pins for VCC and GND. These pins are differentiated by different colors, which enable you to connect your extension module easily. The spread of pins is fully compatible with the Octopus series products.
  • With a voltage boosting module, you can shift the working voltage of P8, P9, and P11~P16 between 3.3V and 5V through the voltage switch.
  • Lead out the serial port, I2C port, and SPI port, among which I2C can connect 3 channels of I2C devices and SPI can connect 2 channels of SPI devices.
  • Available for direct serial port communication between two breakout boards.

  • APPLICATION It is suitable for all conditions that require micro:bit GPIO such as programming education, smart device creation, and so on.

    DETAILS

    Standard GVS Port

    GVS Port

    Among the standard GVS ports, the working voltage of the yellow part(P0~P7, P10)is 3.3V, while the working voltage of the blue part(P8, P9, P11~P16)can be shifted between 3.3V and 5V through a voltage switch. Beneath each I/O port, there are pins for VCC and GND. These pins are differentiated by different colors, which enable you to connect your extension module easily. The spread of pins is fully compatible with the Octopus series products.

    Voltage Switch

    Voltage Switch

    Sliding this switch, we can change the voltage of the blue IO ports(P8, P9, P11~P16)between 3.3V and 5V.

    You can see its working range below:

    Serial Port

    Serial Port

    The working voltage of the serial port is available to be shifted between 3.3V and 5V through the voltage switch. Connect TX to P8,RX to P12. The left pins are bidirectional serial port, which can run both input and output. The right female header is a one-way output serial port.

    Note : To use this port, we have to initialize it according to the program the below:
