1. What is Kalkulators?
Kalkulators is an 8 digit 7-segment display calculator running on 1xAA battery. On USB-C, it can act as a regular numpad/macropad.
The assembly is an FR4 sandwich consisting of a backplate, main PCB and a switch plate. The 7-segment displays are guarded by a smokey acrylic plate. Uses M2 hardware.
