pi-top PROTO+

Simple checks you can make on the pi-top PROTO+ pins and Inventors Kit LED's to find out what may cause dimming or flickering issues and how to fix them.

The LED lights up or flashes and then doesn’t work

  • The LED could have overloaded, creating a short circuit. Check if the power flows through a resistor; a burned-out LED is no longer usable
  • Check the wiring. You could have the jumper going to the wrong pin
  • The LED could be facing the wrong direction. LEDs are polarized so power can only flow in one direction.


The LED is dim

  • Check to see if you used the 330ohm resistor. If you used a 10k ohm resistor, you’re restricting too much power.
