Nova is a tiny RP2040-powered board with a 7x10 addressable LED matrix, designed for creative lighting and microcontroller projects. Compact yet powerful, its perfect for makers and DIY enthusiasts.

To make both the LED matrix circuit board and the control board, [Joekutz] carved out isolation paths in copper clad boards using his homemade CNC mill.

This project is very well documented and has everything available including: circuit board layouts, schematics, PICBASIC source, VB computer interface program, and parts list.

Using one 5×7 LED matrix, or N units, horizontally instead of vertically allows the display of two characters, or 2×N characters. The minimum pattern for lowercase and uppercase letters requires only ...
