[Bill Cuthbert]

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.

This is a custom designed PCB (51.2 x 47.8 mm) for self soldering / assembly of an Arduino Pro Mini, using 15 components and a H-bridge module.
 

• 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
