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: A computer, RfCat and a suitable antenna.
Keep in mind: Half-duplex transceiver with specific bands; not a wideband SDR.

Research notes

Repo confirmed via gh api (GPL-2.0, 297 stars); full KiCad tree confirmed via git tree listing. Device ships without an enclosure (docs/source/enclosureOptions.rst just names a commercial off-the-shelf New Age Enclosures part, not a design file, so no enclosure entry listed). TI product page for CC1111F32 verified 200.

Specifications

Radio capabilities

Radio: TI CC1111; half-duplex digital sub-GHz transceiver
Supported bands: 300–348, 391–464 and 782–928 MHz
Unofficial tuning: 281–361, 378–481 and 749–962 MHz; maker experience, not official bands
Modulation: ASK, OOK, GFSK, 2-FSK, 4-FSK and MSK
Data rate: Up to 500 kbps
RF front end: Receive/transmit amplifiers; 800/900 MHz harmonic filtering
Host connection: Full-speed USB 2.0; controlled by host software

Antenna & expansion

Antenna socket: 50 Ω SMA female; use an SMA antenna, not direct RP-SMA
Antenna supply: Software-controlled 3.3 V, maximum 50 mA
Package requirement: Antenna not included; maker suggests ANT500 as a starter
Expansion: P1 GoodFET-compatible header; pinout in board schematic
Programming pads: GIMME-compatible test points
LED behavior: LED can stay off at idle; indicates transmit/receive data activity

Client & firmware

Factory software: RfCat firmware and CC Bootloader preinstalled
Host tools: RfCat Python client with PyUSB/libusb; Linux access rules documented
Installation caveat: README still says Python 2.7; a current Python 3 environment is unverified here
Connection check: rfcat -r opens the interactive client; d.ping() checks communication
USB update target: Use the YS1 CC Bootloader target, not another CC1111 dongle target
Hardware recovery: P1 pins 7 and 9 trigger bootloader mode per maker FAQ
Design files: KiCad schematic and board files in the maker’s repository

What still needs checking

RfCat documentation contains old Python and operating-system instructions. Confirm the actual client/firmware combination before following installation steps.
Band, modulation and data-rate support do not establish support for every device protocol; this is not a general-purpose wideband IQ receiver.
Complete dimensions, weight, current consumption and a measured RF performance table were not established in this review.
