A fully assembled interface board to enable an Arduino Nano with a super quiet TMC2208 controller to become a Model Railway DCC Turntable Accessory Decoder – control your turntable from your DCC Command Station.
Use this interface with an Arduino Nano and a super quiet TMC2208 controller to create your own DCC controlled turntable.
The TMC2208 stepper motor driver is an advanced, extremely quiet driver giving your turntable / traverser almost silent operation.
This board features
- header pins / holes for 12v DC power connector, supplying power to the Stepper Motor ( ~ 12v ), and transforming down to 5v DC for the TMC2208 controller AND Arduino
- header pins / holes for an Arduino Nano ( v3 )
- header pins / holes for an TMC2208 stepper motor controller
- header pins / holes for a simple sensor ( GND, 5V, I/O connected to D3 on the Arduino )
- header pins / holes for the DCC Input from the track.
This is a complete assembled kit with all the components required, including the TMC2208 but without the Arduino Nano. Click here to purchase an Arduino Nano.
The assembled product contains the following components
- Screw Terminals ( 4 x 2 pin, 1 x 3 pin )
- Header pins ( for Arduino and Stepper Controller )
- 3 Capacitors
- 7805 12v DC to 5v DC convertor ( Heat sink not provided but must be used )
- 1 Diode
- 3 Resistors
- 1 high speed optocoupler ( 6N137 )
- A4988 stepper motor controller
The board will be fully assembled and tested ( using an in-house Arduino ) with the example sketch on the How To Page.
