Questions

How big is the NFC ESP32 V2 PCB?

It measures 90 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the NFC ESP32 V2 use?

62 parts, built around the CH340C, ESP32-S3-WROOM-1-N8, AP2112K-3.3 and BSS138. 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 NFC ESP32 V2 KiCad files?

From the alantrundle/bluetooth_app repository on GitHub, at the commit this page was made from: the board is hardware/NFC_ESP32_V2/NFC_ESP32_V2.kicad_pcb and its schematic hardware/NFC_ESP32/NFC_ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the NFC ESP32 V2 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
