Questions
How big is the GastroSlew FOC PCB?
It measures 88.8 × 70.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GastroSlew FOC use?
265 parts, built around the ESP32-S3-WROOM-1U-N4, MT3608, TPS5430DDAR and M24C64-RMN6TP. 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 GastroSlew FOC KiCad files?
From the murjo06/GastroSlew_PCB repository on GitHub, at the commit this page was made from: the board is GastroSlew_FOC.kicad_pcb and its schematic Encoder PCB/GastroSlew_FOC_Encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GastroSlew FOC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
