Small project inspired by #PIXIE. Software and Firmware compatible but using discrete LEDs instead of dot Matrix modules

This project is inspired by #PIXIE - Chainable, Dual 5*7 Micro-LED Displays!
@Lixie Labs did a great job of writing Firmware for the Attiny and building the whole Environment.
Some main Features:
I have soldered one purple COPXIE with black PCBs from OSH-Park. As also seen on Twitter here:

@davedarko also made some himself. His results here: https://twitter.com/davedarko/status/1335723653045084166?s=20
Got two PIEXIE from @Lixie Labs and also this nice little printed stand. Stand and PIXIE are working fine together with COPXIE in the same chain
These picture may be familiar for you from Twitter (https://twitter.com/tinyledmatrix/status/1282358115078414341). But will also put them here to get a more permanent space.
I designed this little Test jig to program #COPXIE - chainable, dual 5*7 tiny led matrix without needing to solder the Pin header. You can program the Attiny and test the SPI communication afterwards.
This time I used JLCPCB's assembly service. Unfortunately not all parts were available from them. So the QFN (IS31FL3730 LED-matrix driver) is not placed. I had to solder them my self. But overall this servixe is good.
