Set of 3 Wireless Modules NRF24L01+PA+LNA 2.4 GHz with SMA Antenna Range up to 800 m Power Supply 3 to 3.6 V SPI for Arduino and STM32
You already have the maximum available quantity in your cart.
The set of three wireless modules NRF24L01+PA+LNA allows you to build a transmitter, receiver, and other nodes of a wireless network in the 2.4 GHz band. Each module features a PA power amplifier, LNA low-noise amplifier, and its own external antenna with an SMA connector. This enables data transmission over a distance of up to 800 m in line of sight without obstacles. The modules are suitable for wireless sensors, remote control of models, telemetry, or connecting several Arduino boards. They can be connected to MCU, ARM, PIC, AVR, and STM32 microcontrollers.
The control microcontroller manages and configures the module via a four-wire SPI interface, which also accesses the configuration registers. There are 125 channels available and selectable data rates of 250 kb/s, 1 Mb/s, or 2 Mb/s, and the output power can also be adjusted. With 5 V tolerant inputs, the SPI pins can be connected directly to an Arduino IDE compatible board. The module uses GFSK modulation with fast automatic gain control (AGC) and internal filtering. The IRQ interrupt pin can wake the microcontroller from sleep as soon as the module receives data, allowing battery-powered devices to save energy most of the time. Three pieces in the package are sufficient for one control unit and two remote sensors, for example.
- Chip – nRF24L01+ with PA power amplifier and LNA low-noise amplifier
- Frequency – 2.4 to 2.5 GHz
- Number of Channels – 125 selectable frequency channels
- Data Rate – 250 kb/s, 1 Mb/s, and 2 Mb/s
- Range – up to 800 m in line of sight without obstacles
- Power Supply Voltage – 3 to 3.6 V
- Maximum Current – 115 mA
- Interface – four-wire SPI and IRQ interrupt pin
- Modulation – GFSK with fast automatic gain control (AGC)
- Antenna – external with SMA connector and adjustable joint from 0 to 90°
- Compatibility – Arduino IDE and MCU ARM PIC AVR and STM32 microcontrollers
- Package Contents – 3 wireless modules NRF24L01+PA+LNA and 3 SMA antennas
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 pieces in a dry, antistatic bag to protect them from moisture and static electricity.
The set of three NRF24L01+PA+LNA modules is an affordable way to connect several devices wirelessly. The PA and LNA amplifiers along with the SMA antennas offer a range of up to 800 m in line of sight. The modules are controlled via the SPI interface and a range of libraries is available for Arduino IDE. They operate with a power supply of 3 to 3.6 V, so it is advisable to use a 3.3 V output from the control board or a separate stabiliser. This set is suitable for hobbyists, students, and developers who need reliable radio communication between multiple nodes.
