Review on Adafruit Power Relay FeatherWing ADA3191 by Mark Harrison

Revainrating 4 out of 5

Works fine but is prone to failure when the load is inductive

This relay works fine but I have found that when driving an inductive load, in my case it is a large contactor the relay radiates noise to the processor , resulting in errors and reboots. I add a snubber circuit to the relay to mitigate this effect.

Cons
  • Only available in white
