Break the Distance Barrier in Your IoT Projects
Standard wireless modules often struggle with signal drops and limited range, ruining the reliability of your custom builds. The NRF24L01+PA+LNA Wireless Module solves this by integrating advanced signal amplification. Whether you are building a long-range drone controller, a smart grid sensor network, or an industrial IoT monitoring system, this module ensures your data packets reach their destination flawlessly—even at distances up to 1100 meters in open spaces.
Powerful Amplification with PA + LNA
What sets this module apart from standard NRF24L01 boards is the dedicated RFX2401C chip, which includes a Power Amplifier (PA) and a Low Noise Amplifier (LNA). The PA boosts the transmission output up to +20 dBm, while the LNA enhances the receiver sensitivity (up to -104dBm at 250kbps) and filters out background noise. Combined with the included 2dBi SMA antenna, you get a rock-solid, bi-directional communication link that penetrates obstacles better than ever before.
Ultra-Low Power for Battery-Operated Devices
High performance doesn't have to mean high power consumption. Designed for modern smart home and wearable tech applications, this transceiver is incredibly energy efficient. It operates on a low 3.0V to 3.6V logic and features a power-down standby mode that draws a mere 4.2uA. This makes it perfectly suited for battery-powered sensor nodes that need to run for months or even years without maintenance.

FAQ Section
FAQ Section
- Is this a Wi-Fi module that connects to my home router?No. While it operates on the same 2.4GHz frequency band as Wi-Fi, the NRF24L01 uses its own proprietary RF protocol. It is designed for microcontrollers (like Arduino or Raspberry Pi) to talk directly to each other over long distances, rather than connecting to a standard internet router.
- Can I power this module directly from a 5V pin?Strictly no. The operating voltage is 3.0V to 3.6V (3.3V is highly recommended). Supplying 5V to the VCC pin will permanently damage the module. However, the data pins are usually 5V tolerant on most microcontrollers.
- How do I achieve the maximum 1000m+ range?To achieve the maximum range, you must set the data transmission rate to the lowest setting (250kbps) in your code, ensure the modules have a clear line-of-sight outdoors, and use a highly stable 3.3V power supply (adding a decoupling capacitor across VCC and GND is highly recommended to handle the 115mA transmit spikes).
