I have a 1.5" Sparkfun OLED 128x128 and Twist Rotary Encoder Combo that does not seem to work. The first day I got it, i plugged in the quick cables, and boom it was hot! They work separately but seem to get static when together. Serial Monitor right now its all glitchy. I’ve been trying for three days now. Would love a refund or a new one that works. Right now getting this:

Them working separately makes me suspect an i2c pull-up issue (there are currently 3 sets of them active, the C6’s Hardware Overview - SparkFun Qwiic Dev Board ESP32-C6, the Twist’s and the OLED’s)…disable all but one set by severing the trace between the i2c jumper pads on 2 of the 3 items and re-test

If it’s still giving issues after perform an i2c detect/scan and post the results here :slight_smile:
