MicroMotion Decoder
Simplified Hookup Diagram for A Loco Without A DCC Decoder
If your locomotive doesn't have a preinstalled DCC decoder, and you don't need sound effects, you can use the AIRWIRE M15 motion decoder. The M15 is a complete NMRA-DCC 1.5A motor drive decoder plus the AIRWIRE radio receiver. With the addition of a suitable battery, your locomotive is ready to go.
