The easiest ever self build of a fully functional DCC Command station with PCB available on eBay plus only a few parts.
The App formats each DCC packet for transmission via Bluetooth to Arduino Pro Mini connected to a h-bridge to form a simple DCC command station with few parts.
* Control of 1 to 20 locos * Ideal for small to medium size layouts * 2 Amps load drives up to 16 of OO/HO locomotives using H-bridge specified * Add a higher current compatible h-bridge to extend load capacity * Short circuit protected * Automatic over current cut-out, adjustable in Arduino code * Lights and direction * Functions 1 to 8 * Turnout / points / accessories 16 pairs of outputs * Custom naming of your locos * Programming the CV1 loco address * Choose a DC power source to suit scale used (Z/N/OO/HO/O/G) 12v to 20v * Free software for Arduino - no restrictions on use or changes if required * Learn from the code on how DCC commands are used * Easy DIY circuit can be soldered on available 50 x 50 mm PCB (on sale on eBay.uk ) * App forms the DCC packets transmitted to Arduino circuit with 15 components * Continuous DCC data flow from Android device to Arduino * New Arduino sketch * PCB available for purchase on eBay
Further to previous work on DCC wireless systems, I have developed a Bluetooth Command Station linked to a receiver Arduino based circuit with a HC-06 BT module and a LMD18200 H-bridge Motor driver delivering 2 Amps.
The overall cost of parts is around £20 with parts purchased from Ebay. See Instructable: https://www.instructables.com/id/Bluetooth-DCC-Command-Station/
