Questions
How big is the Single layer PCB?
It measures 42.5 × 33.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Single layer use?
20 parts, built around the ESP32-WROOM-32U and AMS1117-3.3. 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 Single layer KiCad files?
From the blijf-weg/PCB_RSSI repository on GitHub, at the commit this page was made from: the board is eerste_versie/single_layer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Single layer design in my own project?
Its repository states no licence, so its author keeps all rights: ask blijf-weg before reusing the design.
