Used these for a MicroPython project. Worked well for me.

These are awesome little boards and they cost almost nothing.Pin out is as follows (pin1 has the square box, and 2 is across from it etc.:1 23 45 67 8Functions as follows:1: Ground2: Vcc (3.3v)3: CE (Chip Enable)4: CSN (Chip Select Not) Active Low - SPI Chip Select function5: SCLK (Clock) - SPI Clock Function6: MOSI (Master Out Slave In) - SPI Data7: MISO (Master In Slave Out) - SPI Data8: IRQ (Interrupt) - Optional, but goes low to indicate that data has arrived, fault has occurred, or write buffer full.These work very well with the TMRh20 branch of the RF24 library. You can get this by searching RF24 in the Arduino library manager. Also look at RF24Network, that adds a networking layer on top of RF24, and RF24Mesh that adds a mesh network function on top of RF24Network. The examples with these libraries are very well done and easy to follow.If you're interested in using these with RPi, you can download the library from github. It has corresponding examples to the Arduino library, and it took only a couple of hours to have my RPi talking to my Arduino using a pair of these radios.You may also consider the PA + LNA (Power Amp + Low Noise Amp) version that is available from the same seller her. One of these is good to use as a hub for the integrated antenna version.

You have to e-mail them to get usage and software information, but these appear very thorough and even include advice on power and range using small Arduino host boards. It doesn't exactly match any of the Arduino headers, but all the source pins are there. Using it well does require more than just a low-power USB connection, but it's absolutely perfect for powered IoT applications and its frequency-hopping capability will be an asset in a noisy environment. Can't beat the price!Not sure what the FCC will say about thousands of these showing up, but again, the frequency-hopping capability makes them good neighbors!

Great wireless product! Inexpensive, handles data well, fast too. I use them as sensor transmitters and receivers. At first, I wasn't to impressed with the range using the built in antenna- but that is easily fixed with any number of kitchen products serving as dish antennas (pick one shaped like a parabola). A simple 7" aluminum strainer ($1.50) with the nrf24 antenna at the focal point increases range by more than 10 times! Only thing that could be better is silkscreened markings for pin identification, but luckily the pinout is the same as the more expensive nrf24 boards.

These units worked great. I thought they'd be cheap and only a few might work due to defects, but they all came out operational. Each one was individually packaged in antistatic bags.I've been using them as transceivers, one of which is in a USB dongle running through an Android tablet with an Arduino Nano, and the other end with a barebones ATMega328P. Have not had any difficulties with the chipset so far using libraries already written for the chipset. Failures with packets dropping are a function of obstacles like brick walls and also distance. These particular units work reliably within about 20 feet.I think the only thing that would make it better would be to include a reference sheet.

I found these very easy to work with with the RF24 library and that library's code samples. I didn't have any issues whatsoever, the communication is stronger than I expected, too, going through a couple walls in my home without trouble. The only trouble I ran into was a little bit of sensitivity to heat as I was melting solder to remove the pins and re-soldering wires into the board. I managed to fry one of these by touching a component that is very near to the pins with my iron.

I had to wire a capacitor to + and - ends on both transmitter and receiver in order to successfully send and receive a signal. Without the capacitor, the volage drops and the transmission fails to complete.

These are astonishingly good for the price. After watching a YouTube tutorial I had them working within half an hour with two arduinos.Take note there are different gain modes. Using the low gain option gave me a range of around 15 ft line of sight, but the high gain option gives over 100 ft (I don't actually have enough open space to see how far it will go).
