Micro Singlet Servo Decoder Board Only
Just the Micro Singlet board.  Requires a servo.  For manual operation a pushbutton or a fascia controller is needed.  If you plan to use DCC you can use a single fascia contoller to initially set up the servo centering while mounting and then remove it. Power is provided from the DCC bus or from 8-24V DC if you just want to use the fascia controller. 
Each unit requires about 0.15 A when moving points and about .025 A when resting.
This is a DCC accessory decoder and uses the switch/accessory keys on your DCC controller.
