Questions
How big is the Locust PCB?
It measures 133.4 × 44.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Locust use?
42 parts, built around the DRV8847RTE, AP63203WU, AP63205WU and USBLC6-2SC6. 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 Locust KiCad files?
From the hlord2000/Locust repository on GitHub, at the commit this page was made from: the board is Locust.kicad_pcb and its schematic CutSheetSensors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Locust design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
