📡 Longruner 3pcs NRF24L01+PA+LNA Wireless Transceiver Module 2.4G with Antenna in Antistatic Foam, Compatible with ArduinoIDE (LKY67) Review

The parts worked correctly as they were plugged into the same outlet as other low voltage parts. The parts are controlled by Arduino MEGA. Due to the PA on the board, they draw more current than the non-PA parts and are therefore sensitive to the length of the GND, +3.3VDC wires. In my experience, if the wires are longer than 5 inches, the module will work erratically, and if the wires are longer than 8 inches, it will stop working at all. To solve this problem, add/solder a 10uF tantalum…

I finally found a good test sketch for this and after that it turned out to be a wonderful project. Wireless Wiegand data transmitter, good connection up to 300 feet when RF power level is set to LOW. I tried to upload a video but this site wouldn't let me so I spent almost half an hour on the Revain site. tried to find the rules of the video and all that came up was the stuff they were trying to sell me. God.

The first thing I noticed was that the pins are labeled. This is not typical of such components and is greatly appreciated. The delivery is super fast, everything is packaged correctly. I mean it came in a protective box and anti-static packaging. I tested all 3 and none had any problems. I could run up to 100 meters with no problems. They worked as soon as I plugged them in, although I used a few tricks to improve performance. One thing that helps is aluminum foil around the circuit to reduce…

These long runner transceivers have good range and are easy to use with Arduino. need portability. I haven't tested the range outdoors, but they communicate from my house to my shed, which is 150 feet away, with no packet loss. Normal NRF transceivers will not work at all in this application.

I was very impressed with the quality and ease of use of these modules. I had a little trouble connecting them at first, but after soldering a 10uF electrolytic capacitor between the module's power pins, they worked great. This problem can also be solved by using the adapter for the nRF24L01 module. Another aspect of this product that caught my attention was the excellent build quality of the parts. The solder joints are very strong and the antennas are well built.

I was skeptical at first, thinking that a large number of wires indicates a complexity beyond my expectations. I just wanted to send a few bytes between two devices and it seemed like overkill. So I went down the rabbit hole with some other radios and found that the cheaper and simpler radios aren't all that cheap (or even simpler) when you factor in the extra antennas and extra hardware needed to power them. . I ended up going back to those radios and trying them out. Hallelujah! They work…
