Questions
How big is the PocketMate PCB?
It measures 55 × 69.8 mm and has 6 copper layers, 1.6 mm thick.
What parts does the PocketMate use?
155 parts, built around the STM32U031K8U6, MAX98357AETE+T, TPS61088RHLR and MAX17055ETB+. 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 PocketMate KiCad files?
From the anand2532/PocketMate repository on GitHub, at the commit this page was made from: the board is hardware/kicad/PocketMate.kicad_pcb and its schematic hardware/kicad/PocketMate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PocketMate design in my own project?
Its repository states no licence, so its author keeps all rights: ask anand2532 before reusing the design.
