nRF24L01+ 2.4 GHz module for Flipper Zero

nRF24L01+ on Flipper Zero: What It Does, Pinout, Setup & Fixes

The Flipper Zero ships with no 2.4 GHz radio at all, so anything in that band — including 2.4 GHz wireless-HID research — depends entirely on which nRF24 module you bolt onto the GPIO header.

Quick answer The nRF24L01+ is a 2.4 GHz transceiver that gives the Flipper Zero a band it doesn't have natively, used for wireless-HID research and other 2.4 GHz protocols. It wires to the GPIO header over SPI (VCC to 3V3 pin 9, GND to GND pin 18, CE to A7 pin 2, CSN to A4 pin 4, SCK to B3 pin 5, MOSI to A6 pin 3, MISO to B2 pin 6), and if you also want Sub-GHz coverage the nRF24 + CC1101 2-in-1 covers both bands on one board.

What the nRF24L01+ adds to a Flipper Zero

Out of the box the Flipper Zero covers Sub-GHz, NFC, RFID, IR and GPIO — but not 2.4 GHz. An nRF24L01+ module fills that gap, enabling research in the 2.4 GHz band such as detecting and analyzing 2.4 GHz wireless HID traffic on devices you own or are authorized to test.

For meaningful range, choose a module with a PA/LNA amplifier stage and an external 2.4 GHz antenna — bare nRF24 breakouts are short-range.

nRF24L01+ Flipper Zero pinout

The nRF24L01+ talks to the Flipper Zero over SPI plus CE/CSN control lines via the GPIO header. A typical mapping:

nRF24 pin Function Flipper Zero GPIO
VCC 3.3 V power 3V3 (pin 9)
GND Ground GND (pin 18)
CE Chip enable A7 (pin 2)
CSN SPI chip select A4 (pin 4)
SCK SPI clock B3 (pin 5)
MOSI SPI data out A6 (pin 3)
MISO SPI data in B2 (pin 6)
IRQ Interrupt (optional)
Always confirm against your specific firmware/app docs — pin maps can differ. A plug-and-play module removes wiring mistakes entirely. See our nRF24 setup guide.

Setup (plug-and-play module)

  1. Power off the Flipper Zero and attach the module to the GPIO header.
  2. Power on and open your nRF24-capable app (or Bruce/Marauder build).
  3. Select the nRF24 function; the app initializes the radio over SPI.
  4. Confirm the module is detected before running any scan.

Common problem: black screen / module not detected

If your Flipper shows a black screen or the app can't find the radio when an nRF24 (or dual CC1101+nRF24) board is attached, it's usually a power/chip-select conflict — common on cheap boards that share power between chips. Full walkthrough: nRF24 black-screen / dual-chip fix.

Boards with isolated power per chip avoid this by design — that's exactly why our dual boards use separate LDOs and chip-select logic.

Which nRF24 board should you get?

Just 2.4 GHz, nothing else: a dedicated nRF24 board. Want Sub-GHz too (recommended): a dual board covers 2.4 GHz and 433 MHz on one PCB.

Frequently asked questions

Does the Flipper Zero have 2.4 GHz without a module?
No. It has no native 2.4 GHz radio. An nRF24L01+ module is required for 2.4 GHz.
nRF24 or CC1101 — what's the difference?
nRF24 = 2.4 GHz; CC1101 = Sub-GHz (300–928 MHz). Different bands, different jobs. Full comparison here.
Why does my Flipper black-screen with the module attached?
Usually a power or chip-select conflict on shared-power boards. See the fix guide.
Do I need PA/LNA?
For usable range, yes — PA/LNA plus an external antenna dramatically outperforms a bare nRF24 breakout.
Is nRF24 research legal?
Testing devices you own or are authorized to assess is legal in most regions. Don't operate against others' devices. Follow local RF regulations (e.g. FCC Part 15 in the US).
