Questions
How big is the HALSPA PCB?
It measures 241.3 × 180.3 mm and has 4 copper layers, 1.58 mm thick.
What parts does the HALSPA use?
10,275 parts, built around the LMV321-TR, CH340C, ADS1115IDGS and TPS566238PRQFR. 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 HALSPA KiCad files?
From the hatlabs/HALSPA-hardware repository on GitHub, at the commit this page was made from: the board is HALSPA.kicad_pcb and its schematic HALSPA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HALSPA design in my own project?
Its repository states no licence, so its author keeps all rights: ask hatlabs before reusing the design.
