Sorry that you are having problems, but you could have contacted me to get support and I could have at least tried to help. The board will only support whatever displays work with the I2S matrix library though
Es tut mir leid, dass Sie Probleme haben, aber Sie hätten mich kontaktieren können, um Unterstützung zu erhalten, und ich hätte zumindest versuchen können, zu helfen. Die Karte unterstützt jedoch nur die Anzeigen, die mit der I2S Matrix library funktionieren (Google translate)

Should have used a through-hole design. No instructions.
This is a kit and the description on Tindie states one should go to the seller's website for assembly instructions. In fact, there are no assembly instructions there. I have a fair amount of electronics knowledge and experience, so was able to assemble it without instructions. Most of the components are surface-mount which makes hand-assembly tedious. You need good magnification, a steady hand, a PCB holder, a solder station with a fine-tip iron and hair-thin solder. Alternately, you can use paste solder and an oven. The surface-mount switch broke after just a few operations. I replaced it with a much more robust through-hole switch. It's all a shame. There is plenty of room on the PCB to have used a through-hole or socketed parts design, which would have made assembly much faster and resulted in a tougher product.
Unless you understand electronics pretty well and have experience with surface-mount soldering, don't buy it.
