NRF24L01 Antenna Pair

This is NRF24L01 2.4GHz Antenna Wireless Transceiver Module. The nRF24L01 is a highly integrated, ultra-low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific, and Medical) band. With peak RX/TX currents lower than 14mA, a sub 26A power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01 provides a true ULP solution enabling months to years of battery life when running on coin cells or AA/AAA batteries. These RF modules are very popular among the Arduino tinkerers. The nRF24L01 is used on a wide variety of applications that require wireless control. They are transceivers which this means that each module can transmit and receive data.

Radio Frequency

The nRF24L01+ transceiver module is designed to operate in 2.4 GHz worldwide ISM frequency band and uses GFSK modulation for data transmission. The data transfer rate can be one of 250kbps, 1Mbps and 2Mbps.

Power consumption

The operating voltage of the module is from 1.9 to 3.6V , but the good news is that the logic pins are 5-volt tolerant , so we can easily connect it to an Arduino or any 5V logic microcontroller without using any logic level converter.

The module supports programmable output power viz. 0 dBm, -6 dBm, -12 dBm or -18 dBm and consumes unbelievably around 12 mA during transmission at 0 dBm, which is even lower than a single LED. And best of all, it consumes 26A in standby mode and 900 nA at power down mode. That’s why they’re the go-to wireless device for low-power applications.
