Questions
How big is the MCL Accel PCB?
It measures 85.9 × 37.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MCL Accel use?
45 parts, built around the ICE40UP5K-SG48ITR50, MAX3485ED, W25Q32JVSSIQ and XL1509-3.3. 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 MCL Accel KiCad files?
From the Aztro-dev/MCL-Accel repository on GitHub, at the commit this page was made from: the board is MCL-Accel.kicad_pcb and its schematic MCL-Accel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MCL Accel design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aztro-dev before reusing the design.
