As you embark on this exciting journey, remember that you’re not just buying a piece of hardware; you’re joining a community of enthusiasts and innovators. The open-source nature of OpenDec02 encourages collaboration, sharing, and continuous improvement, ensuring that your investment not only meets but exceeds your expectations. We’re thrilled to have you on board and cannot wait to see the incredible ways you’ll leverage the OpenDec02 to fuel your passion for model railroading. Here’s to many hours of enjoyment, innovation, and discovery ahead. Welcome to the OpenDec02 family!

Now lets get started.

Step 1: Unboxing and installation

Your board, when it arrives, is preloaded with the latest version of the firmware, so you do not need to bring out your flashing tools or similar. We just need to install it in the locomotive of your choice.

You will need the following tools and materials

• Soldering iron
• AWG28 or AWG26 cables to connect the DCC decoder to your model.
• Side cutter

Here’s how the OpenDec02 DCC decoder needs to be connected to the different parts of the locomotive. This is the most basic setup that will get you started using the decoder.

After having installed the decoder into the locomotive and when you put it on the track for the first time, it will just sit there seemingly unresponsive for a minute or two. This is perfectly normal. It is now trying to figure out what minimum PWM setting it needs to be able to get the locomotive moving. It tries the same thing for a number of times to work out the characteristics of the particular motor that you have in your locomotive. During this time the LED on the decoder will shine yellow, indicating that it is busy doing important stuff.

When this calibration step is ready you can now take your locomotive for a spin. It responds to the default address 3. You are now ready to dive deeper into the world of model train control with OpenDec02. Experiment with different configurations, and don’t hesitate to share your projects and learnings with the OpenDec02 community. Enjoy bringing your model train visions to life with unparalleled control and creativity.
