 For each board the following presets are defined:
 
 * Modded: if any change to the default preset is made.
-* Max Power in Watts: adjust the brightness to approach this max power, depending on the number of LEDs used. Default 10: 5V * 2A = 10W (so it runs fine on USB).

 * Jumper1: If the board contains a jumper, it can define pin behaviour. Eg. select between Infrared and Ethernet.
 * Pins: This module is the central place to assign functionality to gpio pins. Other modules and nodes use the pin assignments made here.
