Questions
How big is the Power PCB PCB?
It measures 101 × 175 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Power PCB use?
96 parts, built around the ESP32-S3, ACS712ELCTR-20A-T, ADS1115BQDGSRQ1 and AMS1117-3.3. 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 Power PCB KiCad files?
From the ICRS/IPRL-Electronics-Hardware repository on GitHub, at the commit this page was made from: the board is PCBs/Power_PCB/Power_PCB/Power_PCB.kicad_pcb and its schematic PCBs/Arm Schematic V2/Arm Schematic V2/Arm Schematic V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask ICRS before reusing the design.
