DC 5V-9V I2C / SPI /Serial Communications interface Sensor Expansion Board Breakout Board for BBC Micro:Bit MicroBit V2
Input voltage: DC 5-9V
Output voltage: DC 3.3V （Only）
Please note: The sensor expansion board only supports 3.3V voltage output
and is only suitable for 3.3V sensors.
Not suitable for 5V sensors.
We specially design this sensor breakout board to make simple connection with the micro:bit main board. It comes with AMS1117 chip. You can connect the external DC5-9V to power for micro:bit development board.
This board not only breaks out all the digital and analog interface in the form of servo line sequence, but also adds I2C、serial port and SPI communication interfaces, very easy for sensor connection.
