 +==== Power Dissipation ====
 +Without any heatsink, 6W of dissipation on the power MOSFETs is possible. With Heatsink more than 20W are possible.

-The LCD loses the signal very easy. It helps, to move the LCD as far to the North as possible before mounting the top PCB with the capacitive touch sensors. +The LCD loses the signal very easy. It helps, to move the LCD as far to the North as possible before mounting the top PCB with the capacitive touch sensors.
