What power supplies do you guys use for the D1 and D1 Minis in your projects.
The D1’s has got the Vin pin so I can feed those directly off the Gate Motor and Alarm Panel, but what about the place where 12 volt is not available or when using the Mini with Max 5 Volt supply.
I use any type of 5v charger , speck sheet say it can handle up to 6v. Just make sure when you use vcc that it does not get spikes, memory serve me it is unregulated.
I am a planning to use the VIN pins on the normal D1. The rated external voltage is 6to20volt DC. I don’t like using more than 12 volt as I have seen parts of the board starting to overheat from about 14 volts.
The D1 mini does not have the Vin pins, so I need a 5 volt supy.
Ah, OK, cool.
Yeah, I put a D1 mini on my gate motor, used a linear regulator to drop the voltage to 5v. But I think that approach causes too much heat, I’ve lost 2 minis now through overheating. Will replace them with nodemcu and see if I can just power them with the 12v.
