- VCC is a range of 1.9V~3.6V, do not exceed this range, otherwise it by destroyed the module.
- Except of VCC and GND，the other pins can be direct connected to 5V Microprocessor's IO, needless level converter. Of course 3V Microprocessor's IO more applied.
- If the Microprocessor isn't hardware SPI interface, could be simulated with ordinary IO.
- If connected to 51 series MCU's P0, there is a 10K Pull-up resistor need others Port needless.
- If Microprocessor IO more than 10mA，need connect 2K resistive divider. It could direct connected to AVR Series.
nRF24L01p(nRF24L01+) with PA and LNA is compatible with nRF24L01+(nRF24L01p),and there are same interface. These add a power amplifier(PA) circuit and Low Noise Amplifier(LNA) circuit, which could transmit longer distances and more stable performance for industry standard. Increased PA and LNA, RF switch, bandpass filter, formed a professional full two-way RF power amplifier, making effective communication for greatly increased. The transmission distance to reach 1000 meter with 2DB Antenna at 250kbps data rate on an open area.

What is nRF24L01?
nRF24L01 is a single-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.
