MakerFocus 3pcs nRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module 2.4G 1100m with Antenna and 3pcs NRF24L01+ Breakout Adapter with 3.3V Regulator on-Board for Arduino

Very easy to set up; good quality materials. I will definitely purchase it again for my next Arduino projects.

I used it with teensy 4.1I was having all kinds of problems with it until I used a separate 5v power supply.Works Great, I am impressed with the speed and distance!//Teensy 4.0 Pin nRF24L01+ Pin----------- ---------------Ground 1.

UPDATE: Spoke too soon - yeah, they work but the range and reliability is horrible - very frustrating. They work great for a while and then just stop (yes, checked for free frequencies - also using dedicated 3.3v supply and tried using power modules too). I really wanted these to work - the modules without these external antennas work ok for me, but was really hoping these would give me even more reliability. Turns out I was better off before switching.*****************Guess I did pretty well compared to many. All three of my power modules worked and two of the three rf24 boards worked without caps. The third wouldn’t transmit or receive AT ALL until I added the 10uf cap across the power pins, but then seemed to work great. Note that (at least on my power modules) the M1 and M0 are labeled the reverse of what I think they should be. So if you are having trouble getting the board to even initialize then might try swapping these.

Great product very popular right now, and it was a generous quantity at a fair price the only complaint I have is that it did not come with any schematics, data sheets or literature to aid and using it to its fullest potential, at least a QR code with a web link to manufacturers recommendations would be appreciated.

Usually people who are into things like this are people who like to tinker. These worked well 50 feet from my house and outside in the summer and winter.

Worked after soldering on a 10µF capacitor to the antenna board across the ground and VCC. Good transmission consistency with an Arduino Uno when powered by 5v from the Arduino board (connected to the small voltage converter board).

came with rf transceiver and antenna but missing the Breakout Adapter with 3.3V Regulator on-Board....

100 feet away from my receiving unit. 3 walls total. I'm using the lowest power setting (setPALevel(0)). You have to have a very good power supply for the units to get the most of them.
