The maker publishes this as a project, not a product listing.
Radio equipment needs certification where you live (FCC, CE, UKCA, ISED, Anatel). Some devices are uncertified or restricted in Brazil. Buyers are responsible for their local law.
Bring along
An ESP32 or the ATmega32u4 PCB with a CC1101 module and an SMA antenna, plus a serial terminal or the web flasher.
Keep in mind
It is beta: the shipped firmware and the published PCB target different microcontrollers, and it includes jamming which is illegal to transmit in most places.

Build it yourself
Open hardware
wrait8 publishes Gerbers + BOM (and a 3D render model) for the Mk.I PCB, but the current Mk.II firmware's PCB revision has no hardware files published yet.
Only PCB/beta/Mk.I has Gerbers+BOM (curl-verified 200); PCB/beta/Mk.II contains only a placeholder 'null' file, so the Mk.II hardware the current firmware targets is not yet published. MCU identified as ESP32 from VSPI-default pin assignments (GPIO18/19/23/5) in SubRabbit/Mk.II/SubRabbit.ino; not stated explicitly in the README.

Specifications
Radio and platform
4
Radio
CC1101 transceiver covering the 315, 433, 868 and 915 MHz sub-GHz bands
Controller
Firmware in main targets an ESP32; the published PCB is designed around an ATmega32u4 (Arduino Pro Micro)
Control
A full command-line interface over serial, with a Web Serial flasher and UI for the Mk.II
Display
None; the tool is driven entirely from the serial CLI
What it does
6
Analyze and monitor
Frequency analyzer to detect active channels, plus RSSI and link-quality monitoring
Raw capture and replay
Record raw RF samples (recraw) and replay them (playraw)
Fixed-code capture and replay
Capture and replay fixed-code remote signals (recsig, playsig) and buffer packets (rec, show, play)
Modulations
2-FSK, GFSK, ASK/OOK, 4-FSK and MSK with configurable radio parameters
Jamming and brute force
Continuous transmission on a selected band (jam) and timing-based brute forcing (brute)
Flipper interchange
Interrupt-driven edge capture with .sub file import and export for Flipper Zero compatibility
Hardware files, status and licence
3
PCB bill of materials
Mk.I PCB uses an ATMEGA32U4-AU, a CC1101 module, an 8 MHz crystal, an SMA antenna connector and a USB-A connector
Project status
Marked beta; the firmware target is changing and a Pro Micro firmware port is still in progress
Licence
MIT
No matching specification. Try a chip name, connector or feature.
What still needs checking
The firmware in main and the published PCB target different microcontrollers, so no single ready-to-flash hardware-plus-firmware combination is documented yet.
Antenna, enclosure, dimensions and power draw are not specified in the sources read.
Jamming and brute-force transmission are illegal in most jurisdictions; use is the operator’s responsibility.
