This is a low-power, highly integrated 2.4 GHz radio transceiver chip made by Nordic Semiconductor.
It's designed for wireless communication over short to medium ranges, supporting data rates of up to 2 Mbps.
It's often used for communication between microcontrollers, like Arduino or Raspberry Pi, and is popular in wireless sensor networks, remote controls, and IoT applications.
PA (Power Amplifier):
The Power Amplifier (PA) increases the output signal power of the module.
It helps to extend the transmission range of the module by boosting the radio signal strength.
The inclusion of a PA in this module allows for longer-range communication than a standard NRF24L01 without a PA.
The Low Noise Amplifier (LNA) amplifies weak incoming signals without adding much noise, improving the reception quality of the module.
It helps the receiver to detect signals that are weaker or farther away.
