Automated road marker: common questions

What microcontroller does the Automated road marker use?

The Automated road marker is built around the ARDUINO_MEGA2560_R3_SHIELD, from the AVR/Arduino family.

How big is the Automated road marker PCB?

The Automated road marker measures 114.2 × 189.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Automated road marker?

61 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Automated road marker design files?

From the bytecod3/automated-road-marker repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Automated road marker design in my own project?

Yes, under the terms of its MIT license, which bytecod3 chose for the repository.

Can I test firmware for the Automated road marker 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.
