5 Channel Radio Remote Control

5 Channel Radio Remote Control

This article is about an easy 5 channel radio remote control circuit based on ICs TX-2B and RX-2B from Silan Semiconductors. TX-2B / RX-2B is a remote encoder decoder combine that can be employed for remote control applications. TX-2B / RX-2B has five channels, wide operating voltage range (from 1.5V to 5V), low stand by current (around 10uA), low operating current (2mA), auto power off function and needs few external parts. The TX-2B / RX-2B was originally designed for remote toy car applications, however it can be used for any kind of remote switching application.
