I haven’t tried the serial trick, but do want to add to the others that I’m experiencing the same thing.
Tested the soldered pads and saw 4v coming from my 18650, but nothing on the other pins.
I’ve got 10 on the way, but I won’t need the recharging circuit, and am just considering powering things from the +/- power traces on my protoboards to get the project ready quickly.
Any downside to this? (Other than not being able to recharge through the esp32c3?
