Questions
How big is the RPiHatHVLVPower PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RPiHatHVLVPower use?
64 parts, built around the ADS1115IDGS, TLV4112ID and TPS22917DBV. 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 RPiHatHVLVPower KiCad files?
From the UMDCMS/SiPMCalibHW repository on GitHub, at the commit this page was made from: the board is RPiHat/RPiHatHVLVPower/RPiHatHVLVPower.kicad_pcb and its schematic LEDPulser/LEDPulser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RPiHatHVLVPower 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).
