I am attempting to wire a Adafruit INA260 to a Heltec Wifi Kit 32 v3.1. I’m unable to do this as it isn’t clear which pins are wired to the secondary i2c. I know that I can wire two i2c devices to a Lora 32 v3.2 without issue, but the pinouts are different between the two boards. I’ve attempted wiring to pins 17 - SCL, and 18 - SDA on header J3, based on various information, no success. I’ve also attempted using pins 5 & 6 on J3, also no success.
Could someone provide an updated pinout diagram, as this is frustrating, as between this and the pins_arduino.h not seeming to line up, I’m ready to either use a Lora board (which isn’t needed for this application), or go over to a Pi (which is overkill for this).
Please help!
