This board facilitates using the display L2F50 of siemens s65 in different constructions. The board is equipped with HEADERS, which are easier to connect than small pads on foil of the display.
Another problem with the display is the supply. The electronics is supplied from 1,8 and 2,9V, and you need almost 10V for the backlight. When you apply this board – you can solve that problem. It consists of a simple converter with a mini choke and transistor BSS138 controlled by PWM of a processor.
