LocoNet Shield: common questions

What microcontroller does the LocoNet Shield use?

The LocoNet Shield is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the LocoNet Shield?

The LocoNet Shield measures 55 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LocoNet Shield?

26 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the LocoNet 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 LocoNet 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 LocoNet 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.
