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 SD-90. This module provides DCC signals to the decoder under control from your tablet or smartphone over Wi-Fi using one of our Apps. All you need on the track is DC power. Additionally you can add a Stanton Associates LiPo battery BPS-420 and BPS v4 Module to provide 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 intermittant operation. Use two BPS-420 for double the operating time.
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
