HiLetgo 4pcs NRF24L01+ Wireless Transceiver Module2.4G Wireless Transceiver Module

I use these modules for transmitting/receiving weather data. They work well with Arduinos (e.g., UNO or Nano) and there are many online sources of code for using them. With their on-board antenna they work indoors, perhaps only with the maximum power setting, depending on walls and other obstructions. Outdoors, you will most likely need versions of this device that have an external "duck" antenna. Apparently some sources of these modules don't use "genuine" NRF24L01+ chips, but these appear to be OK. Generally, I have found HiLego to be a reliable source for products like this, including "duck" antenna versions of the NRF24L01+.

Works well

Works just as described.

Had seen a few other reviews mentioning that all of the chips were bad or that they malfunctioned. I have only tested two of the ones I got so far but they work fine. The reviews mentioning that they were faulty only mentioned that they used example code but didn't mention if they were properly powered. These use 3.3 V not 5V vcc and can be damaged if the incorrect voltage is applied that seems like the most likely issue. After doing research as to how to properly use and write the arduino code for these boards I have had no issues getting the two I have used to work correctly

These appear to be real Nordic chips on boards that are overall well-made. Have received some nRF24 modules in the past that seemed to have been hand-soldered by a child, these are better. However, 1 of the 4 received was DOA/Failure. Not good.These do play well with the libraries, and are functionally the same as boards I have that are 10-12 years old. Power consumption is pretty much spec at all PALevels, and DataRate is in there also. If wanting to replace old, cobwebbed boards, these will work. They are just kinda expensive in the end when they send you duds.

The media could not be loaded. These are NOT Bluetooth transceivers. They simply use the unlicensed 2.4 GHz band for simple remote control applications. I did not get a chance to test these yet so cannot comment on their performance yet. These are transceivers which means each unit can send and receive data at the same time, which is a great feature. These units are good value for money since you get 4 per order.

Spent hours trying to get these things working for a remote control airplane project.After triple checking my wiring, code, and raspberry pi's, I had to give up.I don't know if this is the manufacturer's fault, so I'll leave a couple stars to split the difference.

I've used them to have a raspberry pi's communicate with arduino's. The work great.
