NRF24L01+PA+LNA Wireless Radio Frequency Module with a Range of 1000 Meters

nRF24L01 is a double chip radio transceiver for the worldwide 2.4 - 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator, and Enhanced ShockBurst™ protocol engine.

Output power, frequency channels, and protocol setup are easily programmable through an SPI interface. Current consumption is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode. Built-in Power Down and Standby modes make power-saving easily realizable.

Power supply range: 1.9 to 3.6 V

Size : 15mm * 29mm

1. The range of VCC is 1.9V ~ 3.6V, do not exceed this range, otherwise, the module will destroy.

2. Except for VCC and GND, other pins can be directly connected to 5V Microprocessor's IO without the level converter.

3. If the Microprocessor is not a hardware SPI interface, it could be simulated with ordinary IO.

4. If a module is going to connect to 51 series MCU's P0, a 10K Pull-up resistor needed, (No need for other ports)

5. If Microprocessor IO is more than 10mA，a 2K resistive divider needed. It can be directly connected to AVR Series.
