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.

I'm triing for make works MKR1000 with 4-Channel SPDT Relay, but even if the relay board is connected (via I2C) or not... it's sufficent to insert in the sketch the declaration #include <multi_channel_relay.h> Multi_Channel_Relay relay; to hangs the MKR1000; the most strange fact is that the MKR board hangs right before the bootloader so no serial port is given available and it's impossibile to upload another sketch until putting the board in "bootloader mode".Question by: admin on 2018-12-18 02:23:41
Hi, We see you posted the question in forum, We will update it in forum. thanks.Answer by: admin on 2018-12-18 02:23:41
I need to use this board with an Arduino Due and e Base Grove Shield. Can you confirm that i cn power it with 3.3 V through the Grove connector? And i don't need a 5V power supply? ThanksQuestion by: admin on 2018-12-18 02:23:36
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.Answer by: admin on 2018-12-18 02:23:36
