The contrast for the (optional) LC display can be adjusted using RP1. 

 

Using X3 (VCC), X4 (GND) and X2 (GPIO0 – 3), additional connections to the FMA1125 can 
be made. X2 is connected to the digital input / output pins GPIO0-3 of the TSC. If these are 
to be connected to external circuits, the on-board LEDs can be disabled by opening JP3.
