Questions
How big is the Suspension accel PCB?
It measures 20.6 × 74 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Suspension accel use?
47 parts, built around the ESP32-S3-MINI-1-N8, SN74LVC1T45DCKRE4, AMS1117-3.3 and TLV75533PDBVR-MS. 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 Suspension accel KiCad files?
From the meyerAurelius/telemetry-pcb repository on GitHub, at the commit this page was made from: the board is small_board/suspension_accel/suspension_accel.kicad_pcb and its schematic Car_Circuit/Car_Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Suspension accel design in my own project?
Its repository states no licence, so its author keeps all rights: ask meyerAurelius before reusing the design.
