Research notes

Verified via gh api on 5 colonelpanichacks repos (oui-spy is just a firmware-links README; oui-spy-unified-blue/flock-you/ouispy-foxhunter/Sky-Spy are the real firmware). WebFetch of colonelpanic.tech and the oui-spy-unified-blue GitHub Pages flashing guide confirm the board is a XIAO ESP32-S3 carrier; colonelpanic.tech sells assembled units, DIY kits, and bare 'OUI SPY PCBs' but no schematic/Gerber/KiCad/BOM files were found on the shop, docs site, or in any repo tree (only unipwn_hardware.cpp firmware source, not a hardware-design file). Treat as firmware-open, hardware-closed.

Specifications

Standard board hardware

Processor & flash: ESP32-S3, dual-core Xtensa LX7; 8 MB flash
Antenna: Replaceable 2.4 GHz sticker antenna
Feedback: PWM buzzer
Power & programming: USB-C
Firmware board target: Seeed Studio XIAO ESP32-S3

Reviewed Unified Blue firmware

Documented modes: Six: Detector, Foxhunter, Flock-You WiFi, PCAP, Sky Spy and BLE Sniff
Mode selection: Browser boot menu remembers selection; hold BOOT approximately 1.5 seconds to return
Detector configuration: BLE identifier watchlists; holding BOOT during power-on clears the configuration lock
Reflash caveat: Ordinary reflashing does not clear the detector lock stored in NVS
Wi-Fi PCAP: Rolling 2 MB capture; download through browser dashboard
PCAP channel behavior: Locked-channel mode provides an access point; hopping disables that access point
BLE Sniff limit: Advertisements only; connected BLE data-channel traffic is outside this mode
Capture transfer change: Reviewed README removes binary PCAP-over-USB streaming; use browser download
Sky Spy in this build: Wi-Fi Remote ID; serial JSON output without a Wi-Fi access point
Flock-You interface: USB-CDC and Flask dashboard; this mode has no Wi-Fi access point
Foxhunter feedback: BLE target RSSI and buzzer feedback
Preferences: Selector provides buzzer control and configurable access-point credentials

Installation & host workflow

Browser flashing: Desktop Chrome, Edge or Opera; USB-C data cable and Web Serial
Download channel: Web installer follows firmware committed to master
No serial port: Maker suggests a data cable and BOOT held while connecting
Wrong dashboard: Check the joined Wi-Fi network after changing modes; saved networks can auto-reconnect
Session tools: Hub documents persisted sessions and host JSON, CSV and KML exports
Maps & GPS: Some host workflows use external GPS data; not an onboard GPS specification
Identifier limits: Wireless-signature matches are confidence indicators, not proof of operator or purpose

What still needs checking

Shop and hub still describe four modes and a development capture branch; current installer and pinned README describe six. Confirm the installed build rather than assuming a retail unit has every current feature.
The installer text still mentions PCAP over USB, conflicting with the newer pinned README. Browser download is the documented path in that README; no capture path was tested here.
Standard-board battery capacity, complete package contents, enclosure dimensions and SKU-specific PCB revision are unconfirmed. Battery claims for wearable editions must not be applied to this board.
A blanket receive-only or no-transmission description would be misleading: several modes expose Wi-Fi access points.

Source & revision notes

Maker listing checked Sep 15, 2026. Detailed documentation reviewed Sep 16, 2026. Not hands-on tested.

Price is a dated listing; confirm with the maker.

The maker describes Unified Blue detection modes and a Wi-Fi boot selector. “Passive detection” describes operating modes, not physically receive-only radio hardware.

The shop and current installer describe different firmware generations. Confirm the installed build. Identifier matches do not prove device identity or operator.

Prices read from the maker’s shop on 2026-09-18: US$85 for the assembled multi-mode detector, US$25 for the bare two-PCB set. Both were in stock; other OUI SPY variants on the same page were sold out.

Reviewed Unified Blue source: d57600044d5cbde5562587ccd4829441fec1cb53. Standalone project features and the combined firmware are not interchangeable.
