D1 Mini Pro V1.0.0 Power supply

Open HobbyDev1 opened this issue 4 years ago • 0 comments

Just a question regarding this older version of the D1 Mini Pro: Can I use a 3.3 V power supply instead of 5V? I have a Hi-Link HLK-PM03 Module available. Can I use this as input power at the 3V3 and GND Pin? Many Thanks!
