The gateway between hardware and software for Prometheus mSLA
Apollo is powered by a Raspberry Pi 4B and a Raspberry RP2040.
Currently, we use our Klipper fork, together with NanoDLP to drive the Prometheus mSLA printers.

Questions
How big is the Prometheus PCB PCB?
It measures 184 × 80.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prometheus PCB use?
129 parts, built around the RP2040, W25Q32JVSSIQ, TMC2209 and AP2112K-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 Prometheus PCB KiCad files?
From the TheContrappostoShop/Apollo repository on GitHub, at the commit this page was made from: the board is V360/Prometheus_PCB.kicad_pcb and its schematic V352/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prometheus PCB design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
