  • CC1101 sub-GHz transceiver operates at 18433 MHz for low-power wireless use

MCDODO CC1101 Sub-GHz GPIO Board

This MCDODO CC1101 board is a sub-GHz development accessory designed specifically for Flipper Zero users. It connects via GPIO pins 1 through 8, leaving the remaining pins free for other modules. The compact attachment targets makers and researchers who need extended radio capabilities for testing or analysis. The Flipper Zero device itself is not included in the package.

Thermals noise and power draw

The board operates on 5V power supplied directly through the Flipper Zero GPIO header. Its low-power 12dBi omni antenna is designed for wireless applications without active cooling requirements. Passive operation means silent performance during extended transmission or reception sessions. The efficient design minimises additional load on the host device battery during field use.

Bundled antenna and stand

A 12dBi omni antenna is included to boost transmission range to over 2000 feet and receiving range to 80+ feet. The portable stand cover protects GPIO pins from bending and provides secure antenna storage when not in use. Full-body chamfering on the 3D-printed housing improves grip and overall durability during handling. The plug-and-play design requires no software configuration to function.

Questions about this item

How do I attach the CC1101 board to my Flipper Zero without bending the GPIO pins?

Align the board with GPIO ports 1 to 8 only, press it straight down until seated, then fold the portable stand cover over the antenna to lock the pins in place and prevent bending during handling.

Will the 12 dBi omni antenna need periodic retuning or replacement after extended outdoor use?

The antenna is a passive 12 dBi omni element with no active circuitry; it requires no retuning, and replacement is only necessary if the radome or connector suffers physical damage.

At what distance does the 433 MHz link typically hit its reliable ceiling during continuous transmission?

The supplier measured extended transmission range at 2000+ feet and receiving range at 80+ feet; sustained use beyond those distances will see packet loss increase first.
