WayinTop 2Set Wireless Transceiver Receiver with Tutorial, NRF24L01+PA+LNA RF Module with SMA Antenna 2.4 GHz 1100m + NRF24L01 Regulator + Nano V3.0 ATmega328P Board for Wireless Communication System

I have a project using the unamplified version of the nrf24l01+ module. From what I've read online, these powered modules were supposed to be a 'drop-in replacement', but after several hours of frustration, I finally gave in and gave up trying to use them as such.There is a tutorial that this company links you to that points you to an Arduino library called Mirf that you are supposed to download and use. From what I can tell, this code is fairly old, so I was trying to use the newer libraries instead since they seemed to have what I was looking for (mesh support, p2p, etc)It doesn't like that, for whatever reason. If you stick with the libraries/code from their example, it seems to work just fine. For record, I used SPI.h, RF24L01.h, RF24.h in my original code (most tutorials use these). These are the ones I couldn't get working. I'm sure someone with more experience than I could probably, but I don't have that skill level yet. From the tutorial, SPI.h, Mirf.h, nRF24L01.h, MirfHardwareSpiDriver.h are the libraries that finally gave me the ability to get this thing working (I found zero tutorial videos using this).Anyway, I'm changing my review and score because these are, in fact, not faulty. My comprehension of the devices was at fault. This product shouldn't reflect my incompetence.

The ones I received worked well! Just make sure you switch to the old boot loader on the Arduino IDE before you upload your codes to the Nanos, otherwise it won’t upload. (Just look for some YouTube videos or some quick google searches to figure out how to change the boot loader to the old one)

I uploaded the sketches as written and the wrong output was displayed. No matter what I tried I could not get this to work. I also tried the antenna on a different arduino and that was worse. I think it only may work with this particular type of cheap arduino and apparently not well.update: First, the example sketch that they give is cumbersome in that they want you to use their own objects and code. Instead of the standard RF24 code found everywhere else. So don't use that IMO use the standard code you can find elsewhere.Second, I found that one unit did in fact work! Of course, I had to order another antenna to trouble shoot this. So their product was 50% with my order.My guess is that quality control is not done at the factory.

These arduino boards work well. You just need to be sure to do as other reviewers mentioned and set the processor in the Arduino IDE to "ATmega328P (Old Bootloader)".But these wireless modules had issues for me. They worked well for a couple weeks then suddenly I couldn't get them to communicate. I tried different arduino boards, swapping trans/rec code, but no good.So then I replaced these wireless modules with the shielded version ("MakerFocus 2pcs nRF24L01P+PA+LNA RF Wireless Transmission Module"). These work SO much better.My project has a speaker playing audio. The speaker had a constant annoying buzz when using the standard RF24. But then I switched to the shielded one and the buzzing went away!

I used this to make a DIY RC transmitter receiver for an RC Aircraft. I had no difficulty with the hardware and it synched up just fine with my arduino online account.
