Hi Benzino I supplied this controller. Please let me know when you purchased the controller and I will try and help you.

Further to my Bluetooth version and great feedback from this site, I have now released an updated design of the DCC system using the ESP32 node MCU module instead of Bluetooth. This allows the user to have more than one mobile phone throttle for club layouts etc. For build details, please refer to 'Instructables' website here. The PCB is available to purchase on eBay here. The App is available to purchase on Google Play Store here.

Further to my last post, I have updated the App to include suggestions from this site and other users across the world. The full App is available on the Google Play Store as well as a free version.

Control of 1 to 20 locos Ideal for small to medium size layouts Simplest DCC system ever, yet powerful and flexible 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 (1 to 28 on full App) Full App has editable titles, visibility and momentary options on 28 function buttons Turnout / points / accessories 8 pairs of outputs (16 on full App) Custom naming of your locos Programming the CV1 loco address Add your own accessory addresses Full App has 4 on-screen speed bars for control of 4 locos at a time Add max speed for each loco 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 The App screens are : PCB layout: P Circuit diagram:

Thanks for your suggestion, I have released an updated App with up to 28 functions and optional titles, visibility and momentary operation. There are now 4 programable on-screen speed bars with an improved UI (hopefully!). This version is 'LocoMotive Control' - available on Google Play Store (cost £3)

Thanks for your suggestion, I shall include this in the instructions.

Thanks for your very helpful suggestions - I shall update the App accordingly.

Many other functions could be added to the App - how many would you suggest ?

Hi, I am new to this site, however I would like to inform members of a new DCC Command Station I have developed. It has an Arduino Nano and H-bridge with only a few components on a small PCB. The generation of DCC packets are completed within an Android App. This makes for a very simple hardware design ! The App is free and the components required are available on eBay. The system controls up to 20 locos, 8 functions and up to 16 turnout/accessories. Short address programming is also included. All compatible with small to medium size layouts. Details of this project are on the Instructables and Hackster websites. The free Android App is on Google Play Store - titled 'LocoMotive' Link to Hackster: https://www.hackster.io/user526496/model-rail-digital-dcc-command-station-arduino-and-free-app-52dfab
