Questions
How big is the Picoplus PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Picoplus use?
49 parts, built around the W25Q128JVPIQ, APS6404L-3SQR-ZR, TPS7A2033PDBVR-TP and ABM8-272-T3. 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 Picoplus KiCad files?
From the Badbird5907/picoplus repository on GitHub, at the commit this page was made from: the board is PCB/pico_plus.kicad_pcb and its schematic PCB/pico_plus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picoplus design in my own project?
Its repository states no licence, so its author keeps all rights: ask Badbird5907 before reusing the design.
