Questions
How big is the Pico Balance PCB?
It measures 100 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico Balance use?
42 parts, built around the BMI323, LM74610QDGKRQ1, CSD17577Q3A and MBR1020VL. 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 Pico Balance KiCad files?
From the jacksonyann29/Pico_Balance repository on GitHub, at the commit this page was made from: the board is PCB/Pico_Balance.kicad_pcb and its schematic PCB/Pico_Balance.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico Balance design in my own project?
Its repository states no licence, so its author keeps all rights: ask jacksonyann29 before reusing the design.
