Welcome to Blueridge Engineering. We build a small dead rail receiver that works with the Protothrottle. It allows you to control your large scale trains using battery power. Our device supports DCC, Electronic Speed Controls and Live Steam. No other components are required, the receiver interprets commands directly from the Protothrottle and has a range of over 500ft. You can use any of the large scale DCC decoders, an Electronic Speed Controller, or a combination of the two. The receiver can also control standard R/C servos allowing you to control the speed and direction of live steam locomotives.
Please Note: Due to chip shortages and supply chain issues, the price of Xbee modules has gone up and I will have to raise the price of the receiver and programmer a few dollars when I construct the next batch of boards.
