Available July 2019

US$49.00

You can install this Wi-Fi/DCC Locomotive Motherboard in several HO scale locomotives together with your choice of DCC Decoder with sound. It is particularly suited to the Kato GP35. This module provides DCC signals to the decoder under control from your tablet or smartphone over Wi-Fi our Loco Operator App. You can run from DC track power or you can run from a battery in th locomotive. The Stanton Associates LiPo battery BPS-420 and BPS v4 Module provide excellent full battery operation. Drive the loco onto powered track to automatically charge the battery, then use on unpowered track for at least an hour of intermittent operation. Use two BPS-420 for double the operating time.

Full installation guidance provided. You need to have quite good soldering skills!

Full details of BPS-420 battery and BPS v4 are available from Stanton Associates: http://www.s-cab.com with BPS details at: http://www.s-cab.com/price-list.html

WDMI-52 Wi-Fi/DCC Locomotive Motherboard

This motherboard is designed to provide a solution to the problem of controlling locomotives in a "dead-rail" environment. You can work without power on the track and yet still use your choice of DCC sound or non-sound decoder!

It can be installed within several HO scale model locomotives to provide Wi-Fi control of a DCC Decoder installed in the locomotive. It is compatible with NMRA compliant decoders.

You can then drive the locomotive using our Loco Operator app (Version 3+) or you can use one of our DCCIP Send modules with your existing DCC command station.

The board provides convenient labelled places on which to mount your choice of DCC decoder, a Stanton Associates LiPo battery and a Stanton BPS-v4. Convenient solder points are provided on the board to make all the connections including track pickups (for charging), motor and light connections as well as space and connections for a speaker. Full instructions are provided and the Kato GP-35 is used as an example. However we are sure you will be able to fit the assembly into other locomotives where similar space is available. Once everything is installed functions such as lighting and sound are all controllable from Loco Operator app via Wi-Fi. Also you can program DCC config. variables (CVs) without removing anything or placing the locomotive onto a programming track.

We like Dead Rail because we hate cleaning track! Some of our friends even want to use wooden rails, but you have to put the loco on metal rails to charge unless you add an additional power connector.

When using track power, this unit does not respond to DCC track signals. For an alternative that does, check the WDMI-35

Preliminary Specification - Subject to change until product is released for sale.

Dimensions

Length: 146mm (5.75") Width: 18mm (0.71") Maximum Height: 7.0mm (0.28")

Functions and Modes of Operation

Installs in your locomotive to provide direct Wi-Fi controlled Bipolar DCC to your choice of DCC decoder.

Output Ratings

Maximum Continuous Current: 1.0 Amp.

Power Supply Options

(1) Stanton Associates LiPo battery BPS-420 and BPSv-4. Drive your loco onto powered tracl and it will automatically charge the battery. Two BPS-420 may be connected in parallel to provide longer time between charges.
(2) 11 to 18 Volts DC track power via BPSv-4 bypass mode. This unit does not operate using AC.
(3) Track Power supplied from NMRA Compatible DCC Booster may be used as alternative to DC. The WDMI-52 will not respond to bipolar DCC signals on its power input from the track.

Mounting

Screw holes are provided which will fit some Kato locomotives, or use adhesive mounting tape.

Connections

See manual for full connection information and wiring diagrams.

8-Pin NMRA DCC-Ready female socket. Unit supplies bipolar DCC on track pins (dummy rails). Unit receives Motor, Headlight, Rearlight and Common light signals as provided by your DCC decoder. Decoder speaker is connected separately - see below.
