To make the connection more direct, the sensor shield has led all IO pins at the edge of the micro:bit main board to the 3-pin interface. These offer a simple possibility to connect switches using jumper wires. Label G means GND; V is VCC (3.0-3V); S is signal pin; corresponds to the IO pins of the BBC micro:bit motherboard. There are 3 types of connection methods as follows:Connect the gold rings on the shield to sensor modules with alligator-clamp cables Connect the sensor modules with the pin strips on the shielding with jumper wires.Connect the green connector blocks on the shielding to the lead wire. There are 4 types of power supply methods for shielding and the BBC micro:bit motherboard. Direct connection of the battery casing to the micro:bit main board for power supply.This text is machine translated.
