Questions
How big is the PULSE ENG PCB?
It measures 146.7 × 93.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PULSE ENG use?
153 parts, built around the ATSAMD21J17D-MU, INA226AIDGSR, TPS25940ARVCR and EPC2152. 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 ENG KiCad files?
From the CHESS-mission/PULSE_ENG_PCB repository on GitHub, at the commit this page was made from: the board is PULSE_ENG.kicad_pcb and its schematic Control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PULSE ENG design in my own project?
Its repository states no licence, so its author keeps all rights: ask CHESS-mission before reusing the design.
