Description

Micro bit expansion board with LED work indicator communication IIC or SPI IO BIT teaching programming horizontal adapter board onboard passive buzzer

Product selling point:

1. With Micro:bi interface, it can be directly inserted for use

2. All IO ports are led out through pin headers, which is convenient for expansion and use

3. All ports except power pins can be used as GPIO for digital signals

4. With LED work indicator

Convenient multiplexing of P0 pins through jumper caps

Product parameters:

Product name: Micro:bit expansion board module

Communication method: IIC or SPI
