Elecfreaks Breakout Board for the BBC micro:bit

This product does not Include a BBC micro:bit. The BBC micro:bit can be purchased separately here.

Elecfreaks Breakout Board for the BBC micro:bit is a special kind of breakout board. It can lead out GPIO ports, serial ports, IIC ports, and SPI ports from the BBC micro:bit board. The biggest feature is that it can switch electric level for some GPIO ports, which makes the BBC micro:bit available to be adapted to 5V sensors.

Elecfreaks Breakout Board Features

• Input voltage: 3.3V powered by the edge connector on the BBC micro:bit
• Extends all 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.
• With a voltage boosting module, you can shift the working voltage of P8, P9, P11~P16 between 3.3V and 5V through the voltage switch.
• When the voltage switch is at the end of 3.3V, the max current of octopus:bit depends on its power method. 
• When powered by USB port, the output current is 90mA; when powered by PH2.0 battery port, the output current depends on the battery power ability.
• When the voltage switch is at the end of 5V, the maximum output current of 5V part is 500mA.
• Lead out 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.
