Building the PCB
The PCB is populated on both sides. The LCD, rotary encoder and LED and some other components are mounted on the bottom side. The heatsink I used is available from Reichelt (a German component distributor) and must be cut to a length of around 46mm. The parts must be mounted electrically isolated onto the heatsink You can of course use a different kind of heatsink.
The LCD mounts onto the bottom side of the PCB using a 16 pin single row 2.54mm pitch pin-strip. Put some foam between the main PCB and the LCD as it is only held by the pin-strip. The LCD I used is available from Electronic Assembly. If you are using a different model you will probably have to connect it using single wires.
The pictures below show the populated board's top- and bottom side without the heatsink.
