Description
Operating in the 2.4GHz frequency band, the nRF24L01+PA+LNA serves as a wireless transceiver module. It’s engineered to deliver long-range communication while maintaining low power consumption, rendering it suitable for wireless sensor networks, remote robotic controls, and projects necessitating wireless communication.
Equipped with an onboard power amplifier (PA) and a low-noise amplifier (LNA), the module enhances signal strength and sensitivity, thereby extending its range. With the PA module delivering up to 20 dBm of output power and the LNA module providing a gain of up to 10 dB, the nRF24L01+PA+LNA is capable of transmitting data over long distances, even in environments with background noise.
The NRF24L01+PA+LNA module supports data rates up to 2Mbps and has a maximum range of up to 1100 meters in open space with line-of-sight.
It is recommended to pair this module with the NRF24L01 Wireless Transceiver Socket Adapter Board for ease of powering and wiring.
