Feather OLED 128x64

by jaymgrayson on Sun May 09, 2021 8:33 pm

Have purchased and soldered included headers for Feather OLED 128x64. When I try to run the Circuit Python example I get:code.py output:
Traceback (most recent call last):
File "code.py", line 24, in <module>
RuntimeError: No pull up found on SDA or SCL; check your wiring

I think the soldering looks good. Also the reset button works. Any suggestions moving forward would be greatly appreciated!

Very carefully (i.e. in detail) check the soldering on the 3,3v, SDA and SCL pins, on both boards. Ground seems fine since the rest button works. Post a clear photo of both if you want more eyes on it.

This worked. One of the pins on the RP2040 needed more solder!
