Over the years I have purchased three "2-Channel General Purpose SPDT Relay Shield + 6 GPIO with IoT Interface” boards. One of them has 10-amp relays, one has 5 amp relays and the third I cannot recall.
Quick question: how do I tell them apart?
Also, am I correct that those boards are no longer offered? If so, what present NCD product would be a suitable replacement (must accept Particle Borons)?
