NodeMCU and relay with VIN power Have read a lot of different things online, and I just ain't sure yet.
I'm trying to hook up a NodeMCU to control some relays. And want to power the NodeMCU by the VIN pin.
Anyone know if this setup is possible?
Or should I do it in another way?
Looks fine to me, I don't see any issues, assuming the PSU has sufficient 'grunt' to power both, and most will have.
