The new Pi-SPROG DCC devices

Introduction

Pi-SPROG One is a low cost DCC programmer-controller that connects directly to a Raspberry Pi computer.

Pi-SPROG Nano is a low cost DCC interface to boosters, that connects directly to a Raspberry Pi computer.

Using a Raspberry Pi 2 model B with a WiFi adapter, or a Raspberry Pi 3 model B with built-in WiFi you can easily build a fully featured DCC system with wireless throttles using Apple iPhones/iPods with the WiThrottle app or Android phones with the Engine Driver app. Free versions of both apps are available from the respective app stores. Paid for version of the apps are also available with greater functionality.

Pi-SPROG One

Pi-SPROG One is a DCC interface with an integrated 2.5Amp booster that will drive a wide range of layouts, depending on the total current requirements of the loco fleet and accessories.
You can also connect further boosters such as our own SBOOST II. In this respect it is similar in operation to the SPROG II and SPROG 3.

See the Pi-SPROG One User Guide for more details.

We supply Pi-SPROG One with a 14V 3A regulated power supply and all needed software and instructions for you to set up your Raspberry Pi.

Pi-SPROG Nano

Pi-SPROG Nano is a simple DCC interface that can be used to drive a DCC booster such as our own SBOOST II. In this respect it is similar in operation to the SPROG Nano. The Pi-SPROG Nano can be used for operations mode (on the main) programming, but does not support service mode programming on a dedicated programming track.

Packaging

pi-sprog full

Pi-SPROG One is available as our usual package that includes the Pi-SPROG, appropriate 14v 3A Power Supply, and all software and instructions. This is intended for those users who already own a suitable Raspberry Pi and are happy to configure their own system.
Full instructions to create a suitable Linux image are provided.

Pi-SPROG Full Package
We also supply complete and fully configured and tested systems that will work "out of the box" for those users who do not already have a Raspberry Pi or do not feel so confident in the setup process.
This package includes a pre-configured software set on micro SD card (with your choice of system configuration), a Raspberry Pi 3 model B, Pi-SPROG and power supplies for each unit, plus full instructions.
Just plug the Pi-SPROG onto the Raspberry Pi, insert the SD card, plug in the power and connect via wifi from your iPhone or Android!

Power Supplies

The Pi-SPROG One requires a regulated DC power supply of 12 - 19V. A current capacity of at least 2.5 Amp is recommended.
Our Pi-SPROG One - Complete Package includes an appropriate 14V 3A regulated supply. Alternative supplies are also available - please Contact us to request bundling of other options.
Use of a lower capacity supply (e.g. for a low power dedicated programming setup) will require manual configuration of the Pi-SPROG One's current limit.
A small amount of power is taken from the Raspberry Pi's 3.3V supply, through the GPIO connector. Using separate power supplies in this way guarantees that a problem with the DCC track power supply will not affect the normal operation of the Raspberry Pi.

The Pi-SPROG Nano takes a small amount of power from the Raspberry Pi's 3.3V supply, through the GPIO connector, and requires no external power supply.

In both cases the standard Raspberry Pi power supply should be sufficient, depending on what other peripherals you have connected to your Raspberry Pi.

Software

The Pi-SPROG One and Pi-SPROG Nano are supported by the popular DecoderPro software for decoder programming and layout control.

We have created instructions for configuring the Raspberry Pi Operating system

Instructions to create Raspbian Jessie Linux image for Raspberry Pi 2 model B using a wired network connection.
Instructions to create Raspbian Jessie Linux image for Raspberry Pi 3 model B configured as wireless access point.

Prepared Images

To help users in setting up their system we also sell pre-configured Raspbian Jessie images, including all of the software required, on SD Card.
Select the appropriate configuration of the microSD when ordering - pi-sprog sd
Command Station, preset to support WiThrottle or EngineDriver users via wifi
Program Mode, preset to use a VNC connection to a computer, and also supports one WiThrottle or EngineDriver user for Program verification via wifi
Program Mode, preset to use a local connection of HDMI display and USB keyboard, and also supports one WiThrottle or EngineDriver user for Program verification via wifi

Example System Configurations

Wireless DCC Command Station

Use the WiThrottle or EngineDriver App on your mobile 'phone or tablet to drive your trains.
The Raspberry Pi 3 model B includes builtin WiFi, but a separate USB WiFi adapter is required with a Raspberry Pi 2 model B.
Add a touchscreen, HDMI monitor, mouse and keyboard to use on-screen panels to control the layout (with suitable hardware) or add extra on-screen throttles.
Alternatively, connect through the Raspberry Pi's wired network connection to a PC or laptop running a VNC Client.

Standalone DCC Programmer via VNC

Use a Raspberry Pi with a remote wired or wireless network connection to an external PC or Mac running a VNC Client to operate a standalone programming track, based on DecoderPro, capable of programming virtually any DCC decoder.

Standalone DCC Programmer
