Questions
How big is the PicoRF Blk2B PCB?
It measures 15 × 30 mm and has 4 copper layers, 1 mm thick.
What parts does the PicoRF Blk2B use?
67 parts, built around the NRF52833-QDAA-R7, QMC6309, CJ2305 and ICM-42688-P. 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 PicoRF Blk2B KiCad files?
From the madkoding/slimestuff repository on GitHub, at the commit this page was made from: the board is picoRF Blk2B + MTCS/picoRF Blk2B/picoRF Blk2B.kicad_pcb and its schematic picoRF Blk2B + MTCS/picoRF Blk2B MTCS Mk2/TrackerChargingPort.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoRF Blk2B design in my own project?
Its repository states no licence, so its author keeps all rights: ask madkoding before reusing the design.
