Description

DCC servo decoder, based on traditional (THT - Through Hole Technology) components, for two switches. Processor is ATMEGA16A-PU. Power is stabilized using a LM2595 buck-down converter. Servo power can be switch-off via MOSFETs. Four relays are available to polarize the frog. Two buttons can be connected to manually change the switch positions. The switch positions can be returned to the command station via the RS-Bus.

The decodert is a spin-off of the Opendecoder project. Schematics and board have been converted from Eagle (and slightly modified).
