IS Icstation Simple 2 Channel Radio RC Transmitter Receiver Kit for DIY Remote Control Boat Car Projects

Actually using it to control a couple LEDs to tell me if the garage door is open. I soldered a door open magnet to the transmitter buttons and attached both the transmitter and the receiver to microUSB power sources (5.1v DC) and they seem to be doing fine. Accident wired another transmitter up to a 10v DC power source initially, which released the blue ghost after about 5min. So there’s your limit…Receiver is about 5 feet away and one floor above the transmitter, but that seems to be about the range limit through the floor.

These are slick circuits. Works great. Search TX3E to see data sheet for both. In Chinese, but circuit diagrams are there.

For ever reason it will turn on randomly and make my connected motor go up and down. I thought it was the transmitter doing it so I put a button on it but, something else is interfering it. However a great buy for diy things.

Used on a DIY project for my nephew. Just what I was looking for. Already made another purchase. Note: keep in mind it works only in a very short range (which was ok for my project considering its price)
