MDRRC - II    

Based on a cheap Cortex M3 board (STM32) including touch display and some extra components it is possible to control your digital rail road with DCC (14/28/128 speed steps functions F0..F28) and Maerklin Motorola (15 speed steps and functions F0..F4) locomotive and accesory decoders.

By using the USB interface and S88 bus  MDRRC-II can connect with for example KoploperRocrail or iTrain to control your railroad (automatically). And with a network module it is now also possible to use the Roco Z21 app , Roco WLANMaus or WMC.
