### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Espressif ESP32-C5 | MCU / dual-band Wi-Fi 6 + BLE | https://documentation.espressif.com/esp32-c5_datasheet_en.pdf |
| Texas Instruments CC1101 | Sub-1GHz RF transceiver | https://www.ti.com/lit/ds/symlink/cc1101.pdf |

_Notes:_ Verified via the Tindie listing itself (ESP32-C5, CC1101 sub-GHz transceiver and an unspecified GPS module named in the description; no linked repo/schematic) and a web search for 'Rabbit-Labs C5' / 'sometoms ESP32-C5', which surfaced only a CNX Software writeup and the Tindie page -- no maker-published GitHub org or hardware files found. GPS module and SD card are mentioned but no part number is given, so omitted rather than guessed.
