Flipper Zero CC1101 vs nRF24 vs 2-in-1: Which RF Module Should You Buy? (2026)
Share
PINGEQUA Lab · RF Buyer Guide · Verified August 2026
CC1101 and nRF24 solve different radio problems. CC1101 is a Sub-GHz transceiver used by Flipper Zero's Sub-GHz ecosystem. An nRF24-compatible module adds a separate proprietary 2.4 GHz transceiver path for compatible 2.4 GHz research apps. A 2-in-1 board combines both on one Flipper GPIO module. Choose a dedicated CC1101 if you only need Sub-GHz, a dedicated nRF24 module if you only need nRF24-compatible 2.4 GHz work, and the PINGEQUA 2-in-1 if you regularly use both.
“CC1101 vs nRF24” sounds like a normal product comparison, but the chips are not direct substitutes. They operate in different parts of the spectrum and are used by different Flipper applications. Buying only by antenna size, advertised range, or the number of radios on a PCB often leads to the wrong module.
Flipper Zero is not literally “missing all 2.4 GHz radio.” Its STM32WB55 platform includes Bluetooth LE and 802.15.4 capability. What a separate nRF24-compatible module adds is a different proprietary 2.4 GHz transceiver class used by nRF24-oriented apps and lab workflows.

What CC1101 adds to a Flipper Zero
Flipper Zero already contains a Texas Instruments CC1101 for its built-in Sub-GHz functions. TI specifies the CC1101 silicon for 300–348 MHz, 387–464 MHz and 779–928 MHz ranges, while the actual frequencies you may transmit on depend on your Flipper region and local radio rules.
An external CC1101 module therefore does not add a brand-new radio family. Its value is physical RF design: an external antenna, a board optimized for a specific band, or—in the case of Horizon 433 Pro—an amplified RF front end and dedicated board-level power/signal design.

What an nRF24-compatible module actually adds
The nRF24 family is a different radio category. Nordic's nRF24L01+ is a 2.4 GHz ISM-band transceiver architecture; PINGEQUA's dedicated nRF24 product uses a Si24R1 implementation compatible with common nRF24L01+ workflows.
This is not Wi-Fi, and it is not a replacement for Flipper's Bluetooth radio. Think of it as a dedicated transceiver path for nRF24-compatible proprietary 2.4 GHz protocols and applications.

Why a 2-in-1 module can be better than carrying two boards
A dual-radio board is useful only when the hardware integration is handled cleanly. The PINGEQUA RF Lab 2-in-1 places the CC1101 and nRF24 radio paths on one PCB and uses separate chip-select lines so software can select the intended radio without a mechanical jumper or physically swapping modules.
Some third-party nRF24 apps hard-code GPIO or chip-select assumptions, which can make them partially incompatible with multi-radio boards. PINGEQUA built its own RF Lab app for the board so the supported dual-radio workflow is documented as a complete hardware + software system rather than as an anonymous “multi-board.”

Basic CC1101 vs Horizon 433 Pro
If you already know you need Sub-GHz, the more useful comparison is often not CC1101 vs nRF24—it is basic external CC1101 vs Horizon 433 Pro.
| Feature | Basic CC1101 | Horizon 433 Pro |
|---|---|---|
| Primary role | Simple external 433 MHz Sub-GHz expansion | PA/LNA-equipped 433 MHz external module |
| Core RF platform | CC1101 | Ebyte E07-433M20S, based on CC1101 |
| PA/LNA | Depends on module variant | Integrated in E07-433M20S RF module |
| Antenna | External antenna connector | SMA, 433 MHz-focused antenna workflow |
| Design priority | Cost and simplicity | Power stability, signal path, connector protection and 433 MHz focus |
| Price* | $24.99 | $32.99 |
The E07-433M20S manufacturer rates the underlying RF module for up to 20 dBm and publishes an ideal-condition distance test. That number should not be treated as a guaranteed Horizon 433 Pro / Flipper Zero range claim: final performance depends on firmware behavior, antenna, legal power limits, environment, data rate and the device at the other end.
Does official Flipper firmware support external CC1101?
Yes. Current Flipper documentation states that the Sub-GHz application supports external radio modules based on CC1101 and provides a Radio Settings control for switching between internal and external radio hardware.
That means “you must install custom firmware just to use an external CC1101” is outdated as a blanket statement. PINGEQUA may still recommend Momentum or Unleashed for product-specific features, app compatibility or Horizon's intended PA/LNA workflow, but basic external CC1101 support is present in the official Sub-GHz software path.
Does a 433 MHz CC1101 board cover every Sub-GHz band?
No. The CC1101 silicon itself supports multiple frequency ranges, but a finished RF board is more than the chip. The matching network, PA/LNA design and antenna can be optimized for a specific band.
For example, the Ebyte E07-433M20S used in Horizon 433 Pro is specified for 425–450.5 MHz. Treat a 433 MHz-focused module as a 433 MHz product, not as an automatically optimized 315/868/915 MHz module.
Which one should you buy?
Only need a simple external 433 MHz Sub-GHz board? → Basic CC1101, $24.99.
Want the 433 MHz-focused path with PA/LNA and dedicated RF design? → Horizon 433 Pro, $32.99.
Only need nRF24-compatible proprietary 2.4 GHz? → nRF24 Module, $24.99.
Need both Sub-GHz and nRF24-compatible 2.4 GHz in one board? → RF Lab 2-in-1, $39.99.
Flipper firmware applies region-based transmission restrictions, and legal operation depends on frequency, power, duty cycle and use case. A module's hardware capability is not permission to transmit everywhere it can tune. Use authorized equipment and respect local regulations.
If you are still deciding, compare all PINGEQUA RF modules by host device and radio type instead of buying the board with the longest feature list.

Is CC1101 better than nRF24 for Flipper Zero?
Neither is universally better. CC1101 is for Sub-GHz. nRF24-compatible hardware is for a different class of proprietary 2.4 GHz workflows. Choose by band and application.
Does Flipper Zero already have CC1101?
Yes. Flipper Zero's built-in Sub-GHz radio uses a CC1101. External CC1101 boards are used when you want a different antenna/RF front end or a board optimized for a particular band.
Does Flipper Zero already have 2.4 GHz?
It has 2.4 GHz Bluetooth LE / 802.15.4 capability through the STM32WB55 platform. An nRF24-compatible module adds a separate proprietary 2.4 GHz radio path.
Can I use external CC1101 on official firmware?
Current official Flipper documentation says the Sub-GHz application supports external CC1101 radio modules. Specific third-party boards can still have firmware-dependent features, so check the product's support page.
Is a 433 MHz module legal in the United States?
Legality is not determined by the product name alone. The allowed transmit frequencies and conditions depend on region, power, duty cycle and application. Use Flipper's region controls and follow applicable local rules.
