Questions
How big is the DRILLTEAMYMchanges PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DRILLTEAMYMchanges use?
68 parts, built around the HX711 and S8550. 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 DRILLTEAMYMchanges KiCad files?
From the ICRS/IPRL-Electronics-Hardware repository on GitHub, at the commit this page was made from: the board is PCBs/DRILLTEAM/Drill V2/DRILLTEAMYMchanges.kicad_pcb and its schematic PCBs/Arm Schematic V2/Arm Schematic V2/Arm Schematic V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DRILLTEAMYMchanges design in my own project?
Its repository states no licence, so its author keeps all rights: ask ICRS before reusing the design.
