Questions
How big is the Ssla PCB?
It measures 81 × 49 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ssla use?
221 parts, built around the CY7C68013A-56LTXC, W25Q16JVUXIQ, TLV75533PDRV and USBLC6-2P6. 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 Ssla KiCad files?
From the korken89/ssla repository on GitHub, at the commit this page was made from: the board is ssla.kicad_pcb and its schematic ssla.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ssla design in my own project?
Its repository states no licence, so its author keeps all rights: ask korken89 before reusing the design.
