We've released the Seeed Relay Selection Guide, it will help you choose the relay that best suits your needs.


The Grove - 4-Channel SPDT Relay has four single pole - double throw (SPDT) switches. It only requires low-voltage and low current signals to control those switches. Specifically, you can use 5V DC to control max.250V AC or 110V DC.

We use an on-board STM32F030F4P6 to control the channels separately. The control command is transmit via the I2C interface, the on-board STM32F030F4P6 will parse the command, so that you can control the switch you want.
