nRF2401 是单片射频收发芯片，工作于2.4～2.5GHz ISM 频段，芯片内置频率合成器、功率放大器、晶

体振荡器和调制器等功能模块，输出功率和通信频道可通过程序进行配置。芯片能耗非常低，以-5dBm 的

功率发射时，工作电流只有10.5mA，接收时工作电流只有18mA，多种低功率工作模式，节能设计更方便。

其DuoCeiverTM 技术使nRF2401 可以使用同一天线，同时接收两个不同频道的数据。nRF2401 适用于

多种无线通信的场合，如无线数据传输系统、无线鼠标、遥控开锁、遥控玩具等。

大器、频率合成器，功率放大器等功能模块，需要很少的外围元件，因此使用起来非常方便。QFN24 引脚

封装，外形尺寸只有5×5-NRF2401 single piece of rf transceiver chip is working in 2.4 ~ 2.5 GHz ISM band, chip built-in frequency synthesizer, power amplifiers, crystal

Body oscillator and the function such as modulator module, output power and communications channel can be through the procedures configuration. Chip energy consumption is very low, with-5 dBm

Power launch, working current is only 10.5 mA, received the current work only 18 mA, a variety of low power work mode, energy saving design more convenient.

The DuoCeiverTM technology makes nRF2401 can use the same antenna, and at the same time receive two different channel of data. NRF2401 apply to

A variety of wireless communication occasions, such as wireless data transmission system, wireless mouse, remote lock, remote control toy, etc.
