3Pcs 1100 Meter Long Distance NRF24L01+PA+LNA Wireless Module With Antenna

You have to use the standard caution because you are working with a certain amount of radio frequency i.e. short wires, bypass capacitors, good power supply. The result is a fantastic toy to make data transmission over a long distance.
After I received them (3 modules), they did not work at all. I found from many web that they should put a capacitor ( VCC(3V) to GND) to filter power source. After some modification, They worked well.
I recently bought a few Arduino modules from Banggood. I am very pleased!! NRF operates more than 1.5 km. in a straight line. Arduino nano is perfect. I can buy them in my country too, but they will be 3 times more expensive and of the same quality! For my projects this is the online store. RECOMMENDED!
Great value. Everything appears as described in the listing. Each unit came in individual static bags, which was a nice touch. I have not yet tested everything but it appears to be good quality so I don't expect issues.
very useful stuff
I will use it for RC car
good soldering, will use it for remote control for my rc boat project. Already tested two of them on small distance, and they work just fine, will test on a bigger distance later

Received in good condition. Tried one with the use of an arduino and it worked at close range (have not tried longer range). However, please note that an arduino cannot deliver enough power when the nrf24L01 is sending, not even in low energy mode (" radio.setPALevel(RF24_PA_MIN) " from the example file). Use a condensator (for example 0.33uF) on ground and power to get it working, see picture. Search the internet for more info in this.
havent tried these yet so can't say how good or bad they are.
