Questions
How big is the Drill pcb PCB?
It measures 105 × 103 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Drill pcb use?
49 parts, built around the ESP32-DEVKITC-VE, TBA 2-0511 and SI2333-TP. 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 Drill pcb KiCad files?
From the BrnoMarsRover/Drilling repository on GitHub, at the commit this page was made from: the board is pcbs/drill_pcb_v3/drill_pcb.kicad_pcb and its schematic pcbs/adc board/adc board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Drill pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrnoMarsRover before reusing the design.
