More than a basic CC1101 module

Many external CC1101 expansion boards simply connect a module to the header. They work, but power, signal stability, and connector protection are often simplified. The Horizon 433 Pro optimizes these details:

• A more stable 3.3 V supply for the E07-433M20S
• A 4-layer PCB with optimized impedance matching for cleaner RF and better performance
• Optimized TX/RX state control so PA/LNA works better with the firmware
• Protection and stabilization on the SPI lines
• An SMA connector so you can pair a better-matched 433 MHz antenna
• Clearer status indication so the working state is easy to read

These make the Horizon 433 Pro a proper high-performance external Sub-GHz module for everyday use, rather than a temporary DIY board.

A stronger 433 MHz external experience

The Horizon 433 Pro uses a dedicated 433 MHz RF module together with an external SMA antenna connector, so you can fit the right 433 MHz antenna for your environment.

For Flipper users who need a more stable external Sub-GHz experience, the Horizon 433 Pro is a more professional choice than a basic CC1101 module.

Optimized for Momentum / Unleashed

The Horizon 433 Pro is tuned around how Momentum / Unleashed handle an external CC1101, and works with the firmware's external Sub-GHz settings.

• Sub-GHz → External CC1101
• Firmware → Momentum or Unleashed recommended

Support varies between firmwares. Real-world results depend on firmware version, antenna, environment, and settings.

Clear TX / RX status indicators

Two low-brightness status LEDs make it easy to check the module state at a glance:

• TX / PA — the transmit path is active
• RX / LNA — the receive path is active

The LEDs use a soft brightness, so they are easy to read without being harsh at close range.

SMA antenna connector

An onboard standard SMA connector lets you use 433 MHz antennas of different sizes.

For the best results, use an antenna genuinely matched to the 433 MHz band. Antenna quality, placement, and environment all noticeably affect real performance.

Who is it for?

The Horizon 433 Pro is a good fit for:

• Users already using the Flipper Zero Sub-GHz features
• Users who want a more stable 433 MHz external module
• Users replacing a basic CC1101 expansion board
• Users doing 433 MHz device learning, testing, and debugging
• Users who prefer plug-and-play over soldering flying-wire modules
