AntiHunter DIGI Node — Bare PCB

Drop-in and solder. Easy to find parts. Open source.

AntiHunter is distributed WiFi and BLE intelligence & attack detection. Controlled from its own WiFi, or using Meshtastic radio commands.

Vibration based scans and self-destruct option. Defensive by design. Knows the devices and networks around you, alerts when it matters. Integrates as far or close as you choose.

Description

The bare PCB for the AntiHunter DIGI Node. Unpopulated — you supply the parts and solder it. Simple through-hole assembly, covered step by step in the assembly manual.

Once built, it does everything the assembled node does: WiFi and BLE device scanning, attack detection with tool identification, drone Remote ID, baseline anomaly alerts, LoRa mesh, and triangulation.

Beta support for the dual-band ESP32C5 and active radar detection

Notes

• PCB only. No modules included.
• Regulated 5 V. USB or the BOM's UPS module. No raw battery voltage.
• Antennas before power. LoRa without antenna = damage..
• Sentinel is beta. MAC correlation and triangulation are experimental.
• Lawful use only. Disclaimer.

Warranty

• Fabrication defects only. The bare board is guaranteed against shorts, opens, misdrilled holes, and delamination on arrival. Report within 14 days of delivery for a free replacement.
• No functional warranty. You source, solder, and power the board — assembled operation is on you.
• Not covered. Any failure after assembly; solder, rework, or handling damage; incorrect placement; wrong power, voltage, or polarity.
• Remedy is board replacement, capped at purchase price. No liability for incidental or consequential damages. Firmware as-is under AGPL-3.0. Statutory consumer rights unaffected.
