A few months ago I started a new side project.. After learning #FreeCAD, #KiCAD, #FlatCAM and setting up a small #CNC mill this is one of the first completed components..
This compact circuit board drives two VQB201 16-segment displays using 74HC595 shift registers, while needing just 4 pins on the microcontroller (CLK, MOSI, CS1, CS2).
