## Blueprint

**Open firmware.** Firmware (fork of wardriver.uk rev3, GPL-3.0) and 3D-printed case STL/STEP are public; no schematic or PCB source specific to this SLIM build was found.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-WROOM-32U (x2, on ESP32-DevKitC V4 boards) | MCU | https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf |
| ATGM336H GNSS module | GPS |  |

_Notes:_ 463n7.io product page and the SignalSleuth README describe this as "my revision of Jhewitt's Wardriver," built from two generic ESP32-DevKitC boards, a BW16 module, GPS and an I2C LCD (i.e. wired from off-the-shelf modules, not a bespoke PCB). The upstream wardriver.uk rev3 project sells an official PCB and publishes its production Gerber ZIP (verified 200), but no schematic/BOM for that PCB, and no confirmation the SLIM variant uses that same board, so I did not mark this open-hardware.
