The Addicore nRF24L01 is a 2.4GHz ISM band transceiver. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and enhanced ShockBurst, protocol engine.
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 module has 5V tolerant inputs which allows direct connection of SPI pins.
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).
Specification:
Frequence: 2.4GHz~2.5GHz
Operating voltage: 3 ~ 3.6V Max
Current: 115mA
Multi-frequency: 125 frequency
Support up to six channels of data reception
Package Included:
2*NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module
2*SMA Antenna

Worked great with the flipper zero once properly soldered

The noise is a little higher than I thought it would be but very useful for long distance off-grid communication. They are well built and will last me for a long time. It can be a little complicated to figure out how to use it but after some YouTube videos you will be up and running in no time.

Disappointed as I have ordered HiLetGo products before with little in the way of problems. I have used nRF24L01 & nRF24l01+PA+LNA many time and I have 4 that are pre-wired for prototyping. This pair WILL NOT transmit. But, they receive OK. I have swapped backwards and forwards with my prototype modules and there is just no doubt they are defective straight out of the bag.

If you prefer to avoid tinkering this might not be the device for you however, After a bit of time and lots of testing I was able to get these to work between a pico zero and a nano. Side note these also need their own 3.3v power supply or regulator. Overall testing it works fantastically and through walls and at quite the distance.

It works well.

So, I ordered two of these and wired them up to two Arduinos and they wouldn't talk two way.No matter what I did, tried 4 different libraries, tried direct power to them via a 12V DC through a BUCK tuned to 3.60Vdc then tested it to 5.5Vdc to power it directly: 5 hours of testing, no good.When I switched one or either of the units with a RF24 with an integrated antenna, they receive data from the internal antenna units, but these, with the external antenna, do not transmit back. So ... you can NOT do an ACK back to the sender using these.This makes it difficult since the sender will not repeat until it knows it was sent and I'm using other SPI devices (ethernet ie.) so the radio will be powered off for a few seconds from time to time while my ethernet does API calls for input/output to the system.So, I REALLY wanted these for the external antenna and extended range and even added a high gain external wired antenna and it receives GREAT ... but since they won't transmit (i.e. do ACK replies). not useful.Other people mentioned they got them working with a capacitor, but I'm not going through that, I'll just have to figure out another solution.

I may have received 2 faulty transceivers, but neither of the ones i was shipped were capable of transmitting any data. The arduino's that I tried them on showed signs of trying to transmit, but nothing ever went across. When I tried sending signals to one of these using another nRF24L01 (the ones WITHOUT an external antenna) it received data just fine and consistently, even between rooms. Does anyone have any ideas on what might be going wrong? Ive spend multiple nights going through google searching this and no one else seems to have this issue :/EDIT: I finally realized after a few days of testing (yes I'm embarrassed but willing to admit it) that I wasnt supplying enough power to the transceiver. If you plan on using this with an arduino, be sure to use something besides the on board 3.3v pin to power this. The 3.3v pin is fine for the nRF24L01's without the attachable antenna, but these need more consistent and stronger current to reliably transmit data
