Suitable for use in a microwave :) (just dont turn it on).
Esp32 is an open-source printed circuit board by Infinity6542, from the Infinity6542/CSI-Collection-Utility repository on GitHub, published under the MPL-2.0 licence. It is a 2-layer board of 56 × 35.5 mm with 25 parts on 64 nets, routed with 277 tracks and 49 vias.
It is built around the ESP32-S3-WROOM-1U-N16R2, TP4056 and XC6220B331PR-G, with the PCM12SMTR and USB4105-GF-A among its other parts. Its parts include 8 capacitors, 8 resistors, 3 ICs, 3 connectors and 2 diodes. It belongs with the ESP32 boards of this library.
This is just a with a custom PCB housing an ESP-32 that can be used to extract CSI data. I plan on using Steven Hernandez's ESP-32 CSI extraction tool to do this, obviously with a modified config. The data will be stored on an SD card and the entire system is battery powered. The PCB and battery is housed inside a case that has special cutouts for the switch, USB port, microSD card slot and the antenna. A cable should route from the ESP to the side of the case, which is where the antenna would be plugged in.

It measures 56 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the ESP32-S3-WROOM-1U-N16R2, TP4056, XC6220B331PR-G and PCM12SMTR. 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.
From the Infinity6542/CSI-Collection-Utility repository on GitHub, at the commit this page was made from: the board is PCB/esp32.kicad_pcb and its schematic PCB/esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
