DCC Decoder Shield: common questions
What microcontroller does the DCC Decoder Shield use?
The DCC Decoder Shield is built around the Arduino_Uno_Shield_WTW, from the AVR/Arduino family.
How big is the DCC Decoder Shield?
The DCC Decoder Shield measures 55 × 55 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DCC Decoder Shield?
19 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the DCC Decoder Shield design files?
From the acwright/Wright-Train-Works repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the DCC Decoder Shield design in my own project?
Yes, under the terms of its MIT license, which acwright chose for the repository.
Can I test firmware for the DCC Decoder Shield without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
