Research notes

AntiHunter repo (AGPL-3.0, 674 stars) tree confirmed via gh api: hw/ folder has only 3D-printed enclosure STLs, an assembly-manual PDF and a BOM-Links.md that itself points buyers to 'DIGI PCB — AntiHunter Lectronz Store' for the bare board — no schematic/Gerbers for that PCB are in the repo or linked from it.

Specifications

What the bare board needs

Controller: Seeed XIAO ESP32-S3
Mesh radio: Heltec WiFi LoRa 32 V3.2
GPS: ATGM336H module
Storage and sensors: Micro-SD adapter and card, SW-420 vibration sensor, DS3231 real-time clock
Board: 82 mm round, two copper layers, four 4 mm mounting holes, 10 mm cutout for custom wiring, 2-pin JST digital passthrough
Power: Regulated 5 V from USB or the BOM’s UPS module; no raw battery input
Enclosure: 3D-printable; STL files in the repository

What the firmware does

Detection: Wi-Fi and BLE device scanning, attack detection with tool identification, drone Remote ID, baseline anomaly alerts
Control: Web UI over the node’s own access point (Full firmware) or serial and Meshtastic commands only (Headless firmware)
Mesh: Nodes share detections over Meshtastic and can report to the Command Center companion software
Dual-band: Drop-in ESP32-C5 build adds 5 GHz scanning (beta)
Flashing: Browser web flasher for Chrome or Edge, with stable and beta channels
Meshtastic radio settings: Serial module on, TEXTMSG mode, 115200 baud, board-specific RX/TX pins

Buying and legal

Bare PCB: US$20; US$16 each for 20 or more; ships from the United States
Built tiers: Soldered Core US$180, Parts Kit US$250, Assembled US$350
Warranty: Fabrication defects only on the bare board, reported within 14 days
Licence: Firmware AGPL-3.0; patent pending on the design

What still needs checking

The default access point password is published in the README and is the same on every unit; the maker says to change it before deployment.
Detection range, battery runtime with the UPS module and enclosure dimensions are not stated.
The built tiers’ exact contents were not opened; only the bare-PCB listing was read.
The maker describes the product as defensive and lawful-use only; scanning other people’s devices is regulated in many places.

Source & revision notes

Maker listing checked Sep 17, 2026. Detailed documentation reviewed Sep 17, 2026. Not hands-on tested.

Price is a dated listing; confirm with the maker.

The Lectronz listing is the maker’s own store. US$20 is the bare PCB with 139 in stock on 2026-09-17; the Soldered Core (US$180), Parts Kit (US$250) and Assembled (US$350) tiers are named on the same page but were not opened.

Features were read from the firmware README at commit 3f382cf (2026-09-14). Sentinel, Wi-Fi motion sensing and packet capture are marked beta; MAC correlation and triangulation are marked experimental.

The bare PCB needs the listed modules soldered on. The maker warns that powering the LoRa radio without an antenna damages it.

Firmware reviewed at commit 3f382cfed1322b262a27edcf417159591e56d6d7. The listing photo shows the unpopulated PCB, which is what US$20 buys.
