Questions
How big is the Saturn controller pcb PCB?
It measures 122 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Saturn controller pcb use?
51 parts, built around the RP2040, RCLAMP0524P-N and AMS1117-3.3. 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 Saturn controller pcb KiCad files?
From the misteraddons/Reflex-CTRL repository on GitHub, at the commit this page was made from: the board is PCBs/Saturn/V1.0/saturn_controller_pcb.kicad_pcb and its schematic PCBs/Genesis-6/V1.0/genesis-6_controller_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Saturn controller pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask misteraddons before reusing the design.
