Its main chip is the ESP32-S3-DevKitC-1 J1, from the ESP32 family. Other key parts include the TLV431ASN1T1G, SN74AHCT1G125DBVR, Semtech SRV05-4.TCT, TJA1051T/3,118 and MCP2518FDT-H/SL. By type, the board carries 59 resistors, 32 capacitors, 20 diodes, 10 connectors, 9 ICs and 3 transistors.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
A carrier board an ESP32-S3-DevKitC-1 plugs into, turning it into a vehicle data logger. The dev board brings the MCU and its power; this board brings everything that has to touch a car.

- Two CAN buses at once. One on the ESP32's own TWAI controller, one on an MCP2518FD over SPI — because the S3 has exactly one TWAI and two transceivers on it would only ever give you a choice, not both. - K-line (ISO 9141 / KWP2000) as well, so a BMW/MINI K+DCAN cable is covered end to end. A solder jumper picks whether the aux harness pins carry K-line or the second CAN pair; the two cannot share a wire. -…
