Questions
How big is the BRD3 PCB?
It measures 90 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BRD3 use?
22 parts, built around the HLK-PM01, DHT22 and BC547. 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 BRD3 KiCad files?
From the mFulmini/engineer repository on GitHub, at the commit this page was made from: the board is Modul3/BRD3.kicad_pcb and its schematic Modul1/SCH1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BRD3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mFulmini before reusing the design.
