Questions
How big is the L0003-Wheatstone Bridge PCB?
It measures 64.3 × 19.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the L0003-Wheatstone Bridge use?
20 parts, built around the EJ508A, PPTC041LFBN-RC, SM5819PL-TP and SML-LX1206GC-TR. 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 L0003-Wheatstone Bridge KiCad files?
From the SunDevilRocketry/Wheatstone-Bridge repository on GitHub, at the commit this page was made from: the board is src/L0003-Wheatstone-Bridge/L0003-Wheatstone-Bridge.kicad_pcb and its schematic src/L0003-Wheatstone-Bridge/L0003-Wheatstone-Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the L0003-Wheatstone Bridge design in my own project?
Its repository states no licence, so its author keeps all rights: ask SunDevilRocketry before reusing the design.
