Keyboard

The device keyboard consists of 24 separate keys.

The keyboard is implemented as a matrix keyboard, which is connected directly to the dedicated keyboard

GENIO lines. The power-on key is the same key as the "END" key (when pressed longer -> power OFF or ON).

The keymatrix has six rows and four columns.

Backlights

The main display has two white LEDs and the secondary display has two blue LEDs for display backlight inside

of the display module. Voltage source for backlights is implemented using a white LED driver on the lower

block, which is also used for keyboard backlight.

There is NPN digital transistor which controls which display is lighted at the time. The transistor is controlled

by GENIO03. There is no possibility to turn both display backlights on in the same time.

The driver increases battery voltage up to 18V.
