Questions
How big is the Pulse board PCB?
It measures 81.2 × 84.7 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Pulse board use?
175 parts, built around the ESP32-S3, SN65HVD230D, IXDD609D2TR and LT8606IDC#TRPBF. 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 Pulse board KiCad files?
From the william-richards1/Pulse repository on GitHub, at the commit this page was made from: the board is Hardware/Pulse board.kicad_pcb and its schematic Hardware/Capacitor-bank.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pulse board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
