Questions

How big is the OpenWifiDecoder PCB?

It measures 16 × 23.6 mm and has 4 copper layers, 1.02 mm thick.

What parts does the OpenWifiDecoder use?

64 parts, built around the ESP32-S3-MINI-1-N8, BQ27441DRZT-G1A, ICM-20948 and LTC4054ES5-4.2#PBF. 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 OpenWifiDecoder KiCad files?

From the derGraph/openWifiDecoder repository on GitHub, at the commit this page was made from: the board is openWifiDecoder.kicad_pcb and its schematic openWifiDecoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the OpenWifiDecoder design in my own project?

Its repository states no licence, so its author keeps all rights: ask derGraph before reusing the design.
