Description

When we are doing DIY experiments, we often use the Micro:bit control boards and sensor u[. In order to facilitate the wiring-up, the Micro:bit expansion board are led out the pins for the connection of control board, motors and sensors. Due to anti-reverse interfaces and the fixed wire sequence, the sensor/module won’t burn out. The expansion board has 2.54mm anti-reverse interfaces with silk screen. We supply power through the on-board PH2.54 lithium battery box and an micro USB cable. The power supply voltage is 3.3~5V. In addition, it comes with four 3mm positioning holes, which is convenient to fix on other devices.
