๐ What Can You Do with This?
This jammer is based on the Flipper Zero integrated with the NRF24 module. Thanks to its capabilities, you can effectively suppress signals from various technologies, including:
- Bluetooth ๐
- BLE ๐ฑ
- Drones ๐
- Wi-Fi ๐ถ
- Zigbee๐ก
๐ List of Components
To bring this project to life, you will need the following components:
- NRF24L01+PA+LNA module ๐ ๏ธ
- 16V capacitor rated at 100ยตF ๐
- Step Down Module AMS1117 3.3V
๐งโ๐ง Let's Get Started with Soldering!
One nRF24
HSPI Connection
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | B2 |
| CSN | A4 |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |
| IRQ |
Power Supply Connection
| AMS1117 | Flipper Zero GPIO |
|---|---|
| VIN | 5V |
| GND | GND |
| nRF24 | AMS1117 | capacitor |
|---|---|---|
| VCC | OUT | + |
| GND | GND | - |

Two nRF24
HSPI Connection
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | B2 |
| CSN | A4 |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |
| IRQ |
VSPI Connection
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | C3 |
| CSN | C0 |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |
| IRQ |
Power Supply Connection
| AMS1117 | Flipper Zero GPIO |
|---|---|
| VIN | 5V |
| GND | GND |
| nRF24 | AMS1117 | capacitor |
|---|---|---|
| VCC | OUT | + |
| GND | GND | - |

In both configurations (HSPI and VSPI), the same SCK, MOSI, and MISO pins are used. This is not a mistakeโSPI interfaces can share clock and data lines, while proper operation is ensured by separate control signals (CSN and CE)
Four nRF24
Connecting First nRF24 module

Connecting Second nRF24 module
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | SWC |
| CSN | C3 |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |

Connecting Third nRF24 module
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | C1 |
| CSN | SIO |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |
| IRQ |
Connecting Fourth nRF24 module
| nRF24 | Flipper Zero GPIO |
|---|---|
| CE | 1W |
| CSN | C0 |
| SCK | B3 |
| MOSI | A7 |
| MISO | A6 |
| IRQ |
Power Supply Connection
| AMS1117 | Flipper Zero GPIO |
|---|---|
| VIN | 5V |
| GND | GND |
| nRF24 | AMS1117 | capacitor |
|---|---|---|
| VCC | OUT | + |
| GND | GND | - |

In both configurations (HSPI and VSPI), the same SCK, MOSI, and MISO pins are used. This is not a mistakeโSPI interfaces can share clock and data lines, while proper operation is ensured by separate control signals (CSN and CE)
Anyone who built the device before version 1.4.0, please add the AMS1117 module to your circuit, without it the nrf24 does not work correctly
๐ฅ Installing App
- Download the app from the releases section that corresponds to your firmware.
- Install qFlipper
- In qFlipper, go to the "File manager" section, and transfer the application downloaded from release to a convenient location on Flipper Zero
