DFRobot RFモジュール（ペア）

Datasheet could be expanded with a little more example code in C, but once you got it going it's working very well! When you're using the software to set the board's parameters, don't forget to start the program with administrator rights; otherwise it won't work.

I really like this RF modules. Working distance over 1200 meters. They very reliable and good price too. I recommend this product for all robot communication projects.

the DFRobot RF Modules (pair) is an excellent communication system and at low cost, we use it to transmit electronic displays data such as temperature, humidity, or text giving very good results

Very good product easy to install and configure reach of more than 100 meters 100% recommended
