I've created a draft of the device using bread-board to check if I correctly connected LCD to stm32 nucleo and to have something to do driver development before ordering PCB. In addition I've added to the board up/down/left/right keys.

Connections changes to original schematic:

LCD connection:

• RST - PC7
• DC - PA8
• CS - PB2

Keys:

• up - PC3
• down - PC2
• left - PC14 (TODO: move it somewhere else)
• down PC15 (TODO: move it somewhere else)

I've also tried to solder the part responsible for dimming the LCD but having only MOSFETs in SOT-23 package, it seems to much to work.
