Questions
How big is the Driver v1 PCB?
It measures 100 × 66.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Driver v1 use?
92 parts, built around the OPA314AIDBV, ADA4891-1ARZ, D5V0L1B2WS-7 and SM2000. 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 Driver v1 KiCad files?
From the nmk456/gamma-spectrometer repository on GitHub, at the commit this page was made from: the board is driver_v1/driver_v1.kicad_pcb and its schematic back_panel/back_panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nmk456 before reusing the design.
