“Nrf24L01 based module has been very popular, because it’s easy to implement in wireless communication projects. The module could be found under 1$ with a PCB printed version, or monopole Antenna.The problem with these cheap modules is that they have many issues and become easily defective. Mainly because the IC is not originally made by Nordicsemi, but also because of the poor printing quality of the PCBs.
Throughout this article I will show you how to build your own nrf24L01 based module, and how to add PA (Power amplifier ), LNA (Low noise amplifier) to extend range and output power.”
