This is a breakout board only, nRF24L01 transceiver isn’t include.
The nRF24L01 is a brilliant little wireless module that operates on the 2.4GHz ISM band and has plenty of features packed into a small chip that is usually found on a PCB about the size of half a matchbox. However there is a little issue with some of these boards - they cannot be used on a prototyping breadboard due to the double row header pins used on them.

On-board AMS1117-3.3 voltage regulator
Small power on SMD LED indicator
