Nrf24l01+pa+lna SMA Antenna Wireless Transceiver Communication Module 2.4g 1100m

These worked perfectly. The other ones with printed antennae could only reach 30 or 40 feet reliably. These will reach anywhere on our property through any number of walls. These are my radios of choice. I also recommend the Addicore boards for connecting them.

It came with no information or documentation.DOA. I connected it to the Arduino using the standard pin out provided by many of the web sites for Arduino support and did not work. However when I connected the regular nRF boards everything works fine.Probably pin out is different but I don't have the time to reverse engineer this board

Only giving this three stars to start with because I haven't gone full blown with these yet. Tonight was my first test, replacing an Addicore NRF24I01 pin for pin with one of these, no breakout board involved. I'd been having range problems with the Addicore units, not surprisingly at all, because I simply was trying to get more range out of them than is reasonable. My thought was that using one of these on the receive end would easily increase my range because of the little duck antenna that it has, vs. the printed circuit antenna on the Addicore units. I was totally right... Now I can place the receiver for my wireless lightning detector system basically anywhere in the house. The actual detector and transmitter setup are on my porch and have to transmit through at least a concrete block wall to get to the receiver. I was getting a lot of dropouts placing the receiver here in the bedroom, and now no dropouts at all. That's a really good start, considering that I haven't bothered with the breakout board for higher power use and all that. It's just tapping power from the Arduino Nano's 3.3V output pin as before with the Addicore NRF24I01 units. Note, this is strictly running as a receiver with no error checking, so the TX is NOT running on it. I'm sure that if I tried that, it would fall short on power and fail to communicate.I have a project coming up involving a long distance motion alarm, that will use two of these and will definitely need high power on the TX side. When I do that, I'll be testing it in a large building, with multiple signal obstacles of all kinds. I'll definitely come back to update this review with my results, and hopefully I'll be upping the rating to 5 stars if all goes as I hope.Rick NR417

Works great! The nRF24 radios have a bit of a learning curve as opposed to wifi, but once you begin to understand how these work and start sending/receiving packets, they're well worth the price. The range is superb!These seem to be a Chinese knockoff, but really, it didn't make much of a difference since it performs just as well as the more expensive version.

I was a bit skeptical at first after playing with other nrf24 modules, ones that didn't have an external antenna, the range on those left a lot to be desired. But this little module -- holy #@$@#$. It goes through walls, trees, cars -- anything short of a lead wall. The range WAY exceeded my expectations. I can't even imagine what kind of a range I would get with this if it was paired up with a directional 2.4 Gig antenna. WOW.

probably counterfeit -- doesn't match the photo (board layout is different) and definitely doesn't work (where an onboard-antenna NRF24L01+ module works fine). The board is misprinted with no screenprint on the bottom. Pinouts aren't marked, but they either don't match a typical NRF24L01+ breakout, or the board just doesn't work.

To get reliable high power communication, you need to shield the board. I wrapped mine in black tape, and then wrapped in tin foil that was grounded to the antenna ground. This solved all of the issues I was having.

Got two at ones for a robot build small size for the range and bought two power ragulaters
