I have a circuit with a 3.3V regulator in it. Other esp32 boards work fine, but for whatever reason I cannot power my Lora v2 from 3.3v. What I am doing wrong? it happens no matter which of the two 3.3 pins i am using. It doesnt even work from a lab power supply, so does not depend on my regulator circiut.
Can heltec lora v2 boards run from 3.3V at all?
Help is much appreciated.
