Research 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.

Source files & firmware context

3
Maker CAD
SignalSleuth repository has STL/STEP models; SLIM v1.1 fit unconfirmed
Upstream firmware
Separate A/B programs for the two ESP32s; main is experimental
Upstream releases
v1.2.0 stable includes BW16 support; v1.3.0b2 is beta
What still needs checking
  • Confirm enclosure contents: the product page contradicts itself. Its enclosure minimum is not the assembled device’s dimensions.
  • Board power requirements, final dimensions, weight and exact SLIM/BW16 firmware configuration are unconfirmed.
  • Upstream source is context, not a verified SLIM v1.1 flashing recipe. Confirm A/B placement, BW16 wiring and required configuration with the maker.
