Questions
How big is the MPP1 PCB?
It measures 79 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MPP1 use?
26 parts, built around the ESP32-S3-WROOM-1-N8, LD1117V33 and USBLC6-2P6. 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 MPP1 KiCad files?
From the basimallawala/MPP1 repository on GitHub, at the commit this page was made from: the board is MPP1.kicad_pcb and its schematic MPP1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MPP1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask basimallawala before reusing the design.
