Specifications:
The nRF24L01+ is a 2.4GHz ISM band transceiver
Range: 800+ meters line of sight
Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)
A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps).
The on chip voltage regulator accepts supply voltages from 1.9 to 3.6V.
The module has 5V tolerant inputs which allows for direct connection of SPI pins to the A r d u i n o.
Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).
The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Ar duino), from sleep when the module receives a transmission providing great power conservation in battery devices.
Auto-acknowledge and auto-retransmit abilities
Weight: 13.28 g (0.468 oz)
Board dimensions, excluding pins: 15.5mm (0.61/) width x 40.7mm (1.6/) length x 12.2mm (0.48/) height
Dimensions of antenna, when angled at 90 degrees: 87mm (3.43/) height x 9.5mm (0.37/) diameter

2.0 out of 5 stars Beware faulty pins. Adapter recommended. Great module otherwise. (Tips included)
By Erin on February 17, 2019
When I got these, I immediately jumped into testing them. I had my arduinos set up on two separate breadboards to do a little testing with the interface. I'm fairly experienced with arduino, so this shouldn't have been a problem at all if the hardware functioned properly, but because the connections on the pins were loose, the transmission/reception on one of the boards became choppy, and at one point stopped all together. This turned into a multiple hour ordeal of troubleshooting and trying to figure out if my boards were shot, or if the receivers were faulty. Once I found the fault, I was able to fix the problematic pins and create a really stable connection. If you buy the voltage regulating adapter and get a functioning unit, this thing will work beautifully.

TIPS:

One thing you may notice when interfacing with these through tmrh20's RF24 library, is that it does not recognize the function:

radio.setPALevel()

this is because the function name exists in the RF24.cpp file, but is not being referenced in the keywords.txt file located in the library. To fix this, simply open the file in word pad and save over the file after adding the following line:

setPALevel KEYWORD2

5.0 out of 5 stars Use a 10-220uf Cap across the power leads to function correctly.
By Michael Mona on June 11, 2019
I built 12 units that utilized this NRF24L01+PA+LNA. A couple of things you need to know. Add the cap around the power leads of the unit like the attached picture. If you don't, it will not work. Also, when testing, these units are powerful and sensitive with a range of 800-1000 meters. So testing side by side may not work correctly even at the MIN power setting. Taking the unit 20 to 30 foot away with a couple of walls the way will do it. Best to use separate power supplies for the SBC such as nano, pro mini or Mega, and 3.3-3.6v for the NRF24L01+ PA+LNA. Most Arduino's can not source enough current from their 3.3V pin. KD0ZW
