It's not really new... but finally fully working wiht KiCAD and svg2Shenzhen. Reworked the "classic" 8Bit Mixtape NEO, now with new design, working amplifier 8002 and integrated speaker. Repsoitionend the battery holders, added holes for the speaker and improved the footprints hand-soldering.

Questions
How big is the MixtapeNEO Pixelache PCB?
It measures 98.8 × 64.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MixtapeNEO Pixelache use?
62 parts, built around the ATTINY85-20SU and SK6812. 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 MixtapeNEO Pixelache KiCad files?
From the 8BitMixtape/8Bitmixtape_reworked repository on GitHub, at the commit this page was made from: the board is KiCAD/MixtapeNEO-Pixelache.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MixtapeNEO Pixelache design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
