Hi!
I have several EXP kits and they work great.
However, two of them do not having working 3-wire ports; they are still new. No bumpers, encoders, potentiometers work on A-H ports. I took a multimeter and verified the red and black wire have 5v across.
The same bumpers and encoders work just fine on other EXP brains, just not these two Brains.
I found this thread that had the same issue with the EXP 3-Wire ports.
I’ve tried force firmware updating, factory reset, browser IDE, VS Code extension but still the same result: nothing on the 3-wire sensor port.
I’ve also noticed the 3-Wire icon is missing altogether on the Sensor Dashboard on the two bad Brains:
The working EXP Brains have a 3-wire icon on the Dashboard:
Firmware: 1.0.3
VexCode IDE 2.4.5-15
I was wondering if I may have missed something or needed to update something?
Thanks!
