Set of 3 Wireless Modules NRF24L01+PA+LNA 2.4 GHz with SMA Antenna and 3 Adapters 3.3 V Range up to 800 m SPI for Arduino and STM32
You already have the maximum available quantity in your cart.
This set of three wireless modules NRF24L01+PA+LNA with adapters is ready for building a small radio network in the 2.4 GHz band. Each module features a PA power amplifier, an LNA low-noise amplifier, and an external antenna with an SMA connector for data transmission up to 800 m in line of sight. Each module comes with an adapter board that simplifies powering and wiring connections. The modules can be used for wireless sensors, remote control, telemetry, or connecting multiple Arduino boards. They also work with MCU, ARM, PIC, AVR, and STM32 microcontrollers.
The microcontroller communicates with the module via a four-wire SPI interface, which also provides access to all configuration registers. You can set the frequency channel from 125 channels, the output power, and the data rate of 250 kb/s, 1 Mb/s, or 2 Mb/s. The module's inputs can handle 5 V, allowing SPI pins to be connected directly to an Arduino IDE compatible board. The radio section uses GFSK modulation and fast Automatic Gain Control (AGC), with internal filtering helping to meet radio operation requirements. The IRQ interrupt pin can wake the controlling microcontroller from sleep when the module receives data, helping to save power in battery-operated devices. The adapters have a socket for inserting the module and provide it with 3.3 V power.

- Adapter – board with a socket for the NRF24L01+ module and 3.3 V power supply
- Compatibility – Arduino IDE and MCU ARM PIC AVR and STM32 microcontrollers
- Package Contents – 3 wireless modules NRF24L01+PA+LNA, 3 SMA antennas, and 3 adapter boards
Before connecting, check the power supply; the module is designed for a voltage of 3 to 3.6 V, and do not connect higher voltage to the power pin. Screw the antennas onto the SMA connectors before the first transmission and adjust the joint according to how the modules will be positioned in the device. You will achieve a longer range if the modules are placed higher and there are as few obstacles as possible between the transmitter and receiver. Store unused units in a dry and anti-static bag to protect them from moisture and static electricity.
This set of three NRF24L01+PA+LNA modules with adapters contains everything needed for quickly assembling a wireless network. The PA and LNA amplifiers and SMA antennas ensure a range of up to 800 m in line of sight. The module is controlled via the SPI interface, and you will find a range of libraries for it in the Arduino IDE. The 3 to 3.6 V power supply is conveniently provided by the included adapter boards. This set is suitable for hobbyists and school projects where it is necessary to connect multiple devices without cables.
