HowTo: PCB - Building the pxlDigit_PCB
The idea for the pxlDigit_PCB came to me during the construction of the pxlDigit (article here: https://nerdiy.de/howto-elektronik-sieben-segment-ziffer-pxldigit-aus-ws2812-leds-bauen/). There the pxlDigit is built from single WS2812 LED segments. For this, the LEDs must first be inserted into the 3D [...].
