• By MaverickPT 27/10/2016 This little buggers are alot more powerfull than what i though, i got around 200M range, trough several buildings, and on a high RF noise environment. It will automatically convert your data from serial, send it, receive it, and convert it back to serial, so much work it will save you, i really like them as you can see
