Review on 📡 MakerFocus 3pcs NRF24L01+PA+LNA Wireless Transceiver Module with Antenna - 2.4G 1100m Range for Arduino, including 3pcs NRF24L01+ Breakout Adapters with 3.3V Regulator by Rick Pickering

So the first part - 1 of 3 of my transmitters didn't work. It may have been my fault so I won't turn that down. I spent a lot of time getting them to work. Cons: The form factor is really difficult to manage. You can't connect it to a breadboard. You just have to leave it hanging by the connecting cables, especially when you're just starting out with testing. You MUST place a capacitor between the transmitter's VCC and GND pins. It's not just something special. If you use the Arduino RF24 library, there is a function that you can use to test carrier signals. You can use this to see if your radio is seeing transmissions, if it still can't read them it simply can't understand them because they are sensitive to noise. Set PALevel to min, disable LNA and make sure the capacitor is installed. You can also use the test carrier function to find a channel that is not yet showing noise or interference. This will greatly improve your connection. Pros: There is a lot of documentation about it. Just read the available features! Great: When these modules work, they work fantastically through walls and long distances. The processing is good. Yes, I had a broken one, but it could easily happen if I tried really hard to get it working the first time. I will buy more in the near future.
