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

Works well; I didn’t think they were communicating correctly until I utilized a basic test code. Apparently I had a conflicting pin assignment that made it appear that my packets were not transmitting correctly in my larger code. Changed my pin assignments and voila! Additionally I soldered a 10uf capacitor between VCC and ground. Haven’t tried it without the capacitor yet.

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+.

Boards work well for Arduino, just be sure to power them properly with 3.3V.

Works well

Works just as described.
