Questions
How big is the Turbofrank m1p2 PCB?
It measures 99.5 × 99.5 mm and has 4 copper layers, 1 mm thick.
What parts does the Turbofrank m1p2 use?
224 parts, built around the RP2040, RP2350A, LM358 and PAM8403DR. 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 Turbofrank m1p2 KiCad files?
From the rh1tech/frank-archive repository on GitHub, at the commit this page was made from: the board is turbofrank_m1p2/turbofrank_m1p2.kicad_pcb and its schematic frank_fastbeta_m1/audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Turbofrank m1p2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rh1tech before reusing the design.
