— RESOLVED —
The title says it. None of my four Heltec WiFi_Kit_32_V3 boards will power-up from USB. I have three USB_C-to-USB_C cables that all work fine to power-up MicroProcessors with USB_C port. The cables are also used, of course, to successfully upload code MANY times. They-re good. I’ve also plugged the cords into a hefty USB_C charging port but that does not work either.
It seems implausible that none of them power-up because they are all ‘broken’. I feel like there must be some secret I don’t know and haven’t been able to find.
Q1: Am I correct to expect this model of board to power-up when (only) a USB_C cable is plugged into it?
Q2: If not, why not? What do I need to do to make them work properly? Is there some pin or pins I need to pull low or high, or connect to each other.
Q3: Have YOU used this board successfully? On the crazy, off-chance, that I need a VERY unusual and special cable, PLEASE tell me what manufacturer and model I should buy.
This is pretty absurd. I’m on the verge of throwing them in the trash, but I REALLY like the screen on them. It would be VERY useful for several of my projects. So…
ANY HELP would be very much appreciated.
