The unit is intended for installation in battery powered locomotives with 10-16 Volt batteries.

You can install this Wi-Fi/DCC Interface in many HO or other scale locomotives together with your choice of suitable Sound or Non-Sound DCC Decoder. This module provides DCC signals to the decoder controlled by hand-held throttles supporting the Hoffman WiThrottle protocol as used by JMRI. Examples are WiThrottle on Apple IOS, Engine Driver on Android and the popular TCS UWT-100 Universal Wi-Fi Throttle. DC power can be supplied from a 12 volt battery. YOU DO NOT NEED TO INSTALL JMRI!

This module can be installed within many HO or other scale locomotives where continuous running current is no more than 1 amp and provides Wi-Fi control of a DCC Decoder installed in the locomotive. It is compatible with NMRA compliant decoders.

You can drive the locomotive using the Engine Driver app by M. Steve Todd on Android phones or tablets, WiThrottle app by Brett Hoffman on Apple IOS iPhones or iPad and the new and popular TCS UWT-100 Universal Wi-Fi Throttle. You can also use the WifiTrax Loco Operator app.

Functions such as lighting and sound are all controllable from your hand-held device with custom function naming which provides labels for your chosen app or hand-held throttle Wi-Fi. In fact the capability is similar to our WFD-30 except that you only have one locomotive in which the WDMI-32 is installed. You can install these modules in as many locos as you like and each loco then appears as its own WiThrottle server.
