Attention: There this an error on PCB rev1 (if you got it form me in Lecco you should have rev1) 6 LEDs pair got mixed up, and ended up n parallel instead of anti parallel. So expect some glitching Pixels
More Documentation is comming soon.......

Questions
How big is the HAD COM MATRIX PCB?
It measures 64.5 × 28.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HAD COM MATRIX use?
222 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the HAD COM MATRIX KiCad files?
From the tinyledmatrix/communicatorMatrix repository on GitHub, at the commit this page was made from: the board is Hardware/HAD_COM_MATRIX.kicad_pcb and its schematic Hardware/HAD_COM_MATRIX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HAD COM MATRIX design in my own project?
Its repository states no licence, so its author keeps all rights: ask tinyledmatrix before reusing the design.
