Grove - 4-Channel SPDT Relay, switch
Who Viewed This Also Viewed
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.
We've Released the Grove Selection Guide and hope to help you find the Grove suit you best.

Hi, We see you posted the question in forum, We will update it in forum. thanks.
Hi there, if you connect the due, it looks work. but there is current leakage on the relay board. So we do not suggest use the 3.3v for the module. thanks.
