This is a small unit with big power - only 36 components fully assembled on a lead-free circuit board. The enclosure is 95 x 62 x 60 mm

This unit plus App gives a complete DCC controller with features that beat more expensive systems.
Value for money, reliable, simple to use, customise the system to match your roster of locos.

• Install App on an Android device (phone or tablet)  
• 4 digit addressing, CV read/write, program on the main, make consists
• Plug in a DC 15 volt power source
• Control up to 4 trains at a time with many others running in the background
  
  What is different about this system ? 

A very simple electronic circuit provides the DCC signal and power for the track, however the App does the real work !  The computer on your phone is utilised to the full by constructing the codes required to form each packet of instructions, thus simplifying the job of the controller !
This revolutionary system compiles the operating DCC packets within the App which are sent to the Microcontroller interface to combine with the DCC clock signals.  

App features include:

• Roster list contains up to 100 locos with short or long address
   
• Ideal for small to medium size layouts2.5 Amps load drives 12 or more of OO/HO locomotives (more on Z or N gauge)
   
• Short circuit protected
   
• Automatic overload cut-out
   
• Lights and direction
   
• Functions 1 to 32 
   
• Turnout / points / accessories 255 pairs of outputs
   
• Custom naming of your locos
   
• Read / write CV's 1 to 1024
   
• Add your own accessory addresses
   
• Editable titles, visibility and momentary options on 32 function buttons
   
• 4 on-screen speed bars for control of 4 locos at a time
   
• Add max speed for each loco
   
• Long address (1-9999) and short address (1-127)
   
• Program on the main
   
• Form a consist (double head your locos)
   
• Powered by Arduino
  
  NB: App works on Android 10 upwards.
  App is not compatible with Apple iOS

Sample Reviews:

A very comprehensive controller at a fraction of the cost of a stand-alone unit. Excellent customer service too: I suggested a couple of features I'd like and a few weeks later there they were in the latest version! Highly recommend.

Cheap, but powerful, introductory unit for DCC train control. The main interface, with the ability to control four of your locomotives _without leaving the screen_ works very well. The ability to export the config to other machines is very useful when changing devices. I've used this happily with N, OO and O gauge locos. Developer support is second to none!

This Base unit and App work together brilliantly, although I am still working out how to use this myself, I cannot recommend it enough for a DCC system! After a few teething problems, nothing to do with the APP or base unit I might add, (problems with Google play downloading it) the help and service I received from Bill was second to none.

I'm a total novice to dcc. I'm loving the app and most of all the support from the developer Bill is second to none. Quick to respond to any of my queries and very patient with me. Great value too. Thanks for breathing new life into my hobby.
