Its main chip is the ATmega328-P, from the AVR/Arduino family. By type, the board carries 4 jumpers, 4 resistors and 2 connectors.

From the project

This repo contains all the information regarding to the model trains project

For this modele, I use the SBC-USR-ES1 module and the Arduino AT Mega 328.

Here is the circuit board of this project.

Here is the code of the Lights-Shild, using the SBC-USR-ES1 module module. The IP definied for this module is start and you have to change in code:

Lights-Shild: common questions

What microcontroller does the Lights-Shild use?

The Lights-Shild is built around the ATmega328-P, from the AVR/Arduino family.

How big is the Lights-Shild PCB?

The Lights-Shild measures 100.3 × 118.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lights-Shild?

37 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lights-Shild design files?

From the martinfantini/ModelTrains repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lights-Shild design in my own project?

The repository has no license, so all rights stay with martinfantini. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Lights-Shild 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.
