4PCS NRF24L01 2.4GHz Wireless Transceiver RF Transceiver Module With Keyestudio Packing Box for Arduino

This pack of four NRF24L01 2.4GHz wireless transceiver modules is an ideal solution for students, hobbyists, and makers looking to establish reliable, low-power wireless communication between microcontrollers. Designed to work seamlessly with Arduino and other development boards, these compact modules enable both transmission and reception for multi-node projects.

Quad-pack for multi-node networking

This kit includes four NRF24L01 wireless modules, allowing you to build multi-device networks or set up two complete transmitter-receiver pairs. Because each module functions as both a transmitter and a receiver, you can easily establish two-way communication between your Arduino boards.

Low-power wireless communication

Operating on the global 2.4GHz to 2.5GHz ISM band, these modules are highly efficient, drawing just 11.3 mA in transmit mode at 0 dBm and 12.3 mA in receive mode. When not in use, they can be placed into power-down mode where they consume a mere 900 nA, making them excellent for battery-powered projects.

SPI interface configuration

The output power, channel selection, and protocol settings of the transceivers are fully configurable via a standard SPI interface. This allows for straightforward integration with your microcontroller's SPI pins, giving you precise control over your wireless link.

Integrated curved antenna

Each module features a built-in curved antenna that supports a communication range of approximately 20 to 25 metres in an open field when set to 0 dBm transmit power. This makes them ideal for indoor robotics, smart home prototyping, and close-range telemetry.

High-speed data transfer

With a maximum data transfer rate of up to 2000 kbps, these modules can handle rapid data transmission for real-time sensor monitoring. The receiver achieves a sensitivity of -85 dBm at a transfer rate of 1000 kbps, ensuring reliable signal reception.

Compact physical dimensions

Measuring just 29mm by 16mm by 13mm, these ultra-compact modules fit easily onto breadboards, custom PCBs, or inside tight robot chassis. They operate at a safe supply voltage of DC 3.3V, compatible with standard low-power microcontroller rails.
