Questions
How big is the To order PCB?
It measures 220.2 × 164.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the To order use?
166 parts, built around the TEENSY 4.1, ACS713ELCTR-30A-T, ACS758LCB-100U-PFF-T and BME280. 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 To order KiCad files?
From the ryos17/robosub-ee repository on GitHub, at the commit this page was made from: the board is gen3/PCBs/to_order/to_order/to_order.kicad_pcb and its schematic gen1/PCBs/Compute_Power_Board/Compute_Power_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the To order design in my own project?
Its repository states no licence, so its author keeps all rights: ask ryos17 before reusing the design.
