Start LED
Turn on when the start button is pressed or the start module
signal is low (Active Low).
User LED
Programmable LED.
Can be turned on/off from the user program.
Potentiometer
Connected internally to analog input.
Can be used to fine tune the robot speed, sensor threshold, etc...
Mode Selection
DIP Switch
3-Ways DIP switch provides up to 8 configuration.
Can be used to select different tactic/mode for competition.
