The on board IMU (gyros and accelerometers) are on the 12C bus. I looks like you are moving the 12C bus to GPIO 4&5 so the IMU code can no longer get data from the IMU on GPIO 18 & 19 casing an Errno 5. ---

Missed one thing… brand-new out of the box… no code changes, all ports setup properly, 19 other one setup the same exact way and they all work… Any suggestions? ---

Oh, and If I insert the i2c scan in the code (inside of the imu.\_getreg() function), the scan does not list anything… Wondering if there a hardware issue? ---

removed all code from the PICO, and rebuilt from another one… everything works now.
