Relè control

IoT
1

Hello everyone.

With my flint 2 i would like to control a relay via the usb power supply. I would like to deliver it via the /sys/class/gpio/usb_power/value setting. I will have to control a 220v load.

What do you recommend i buy? is there a ready-made module or do you have to make the PCB?

Thanks

Is using USB power-on and off to control the relay? This may require you to DIY or look for.
