Questions
How big is the Emb2 PCB?
It measures 65 × 26.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Emb2 use?
12 parts, built around the ESP32-C3-WROOM-02-H4, HLK-PM03 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 Emb2 KiCad files?
From the NEHASHRIV26/IOT_PCB repository on GitHub, at the commit this page was made from: the board is emb2.kicad_pcb and its schematic emb2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Emb2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask NEHASHRIV26 before reusing the design.
