Led Scroller Matrix, ATMega48-based

A charliplexing-driven 47x8 led matrix made with an atmega48p. With only a few resistors and ~400 leds it’s a pretty decent scroller board* to display messages or act as a pixel-driven screen (but also a little bit tedious to solder by hand!).

Can also be controlled via I2C and includes native scrolling text capabilites on the firmware.

(*): Probably not
