Keyestudio micro bit relay breakout board has integrated a 4-way 5V relay module, fully compatible with micro bit development board. It can work only need to insert micro bit into keyestudio micro bit relay shield, then input DC 5V voltage on the relay VIN GND port, pretty simple and convenient.
4-way relay on the board is active high. Its control terminals are respectively connected to P4, P3, P7 and P6 of the micro bit development board. You only need to control the high or low output level of P4, P3, P7 and P6 , thus control the 4 relay on/off.
