Description

The NRF24L01 is a single chip radio transceiver for the world wide 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 a 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 makes power saving easily realizable.

A PCB with a minimum of two layers including a ground plane is recommended for optimum performance. The NRF24L01 DC supply voltage should be de-coupled as close as possible to the VDD pins with high performance RF capacitors, see Table 16.It is preferable to mount a large surface mount capacitor (e.g. 4.7mF tantalum) in parallel with the smaller value capacitors. The NRF24L01 supply voltage should be filtered and routed separately from the supply voltages of any digital circuitry.
