Expansion Board for Micro:bit GPIO Expansion Python IO:bit 5V with On Board Passive Buzzer

1. IO: bit expansion board is a powerful micro:bit expansion board, which leads to 19 PIN pins of the Microbit Board. 

2. Each PIN pin has VCC and GND corresponding to it. You can freely switch VCC to 3.3V or jumper cap. 5V; with 3 independent 3V3 and 5V pins, the wiring is more flexible and diverse; 

3. I2C SDA and SCL pins and the corresponding 5V and GND pins are provided for module 

connections such as LCD1602 LCD display for I2C communication more possibilities; 

4. With on-board passive buzzer, connected via jumper cap; 

5. Power supply method includes DC head and USB socket power supply.
