Description

The pinout for the Heltec_wifi_kit_32_v3 is incorrect.... https://heltec.org/project/wifi-kit-32-v3/

it seems like the pins_arduino.h file is a copy paste of the V2, but with the V3 board there is an updated pinout

Please update the pins_arduino.h file so the board will work

They updated the pintout, please fix

Debug Message

will not send the correct info to the board but will not give error

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

Hi @smerkadidit, if possible please open a PR with the fix of the pinout for Heltec_wifi_kit_32_v3. Thanks

I was trying to figure that out still. I got the TX and RX pins sorted but some of the others I havent figured out yet.

They have a pin map but admittedly, im newer to this platform to trying to figure it out still
