Traffic: common questions

What microcontroller does the Traffic use?

The Traffic is built around the ATtiny45-20P, from the AVR/Arduino family.

How big is the Traffic PCB?

The Traffic measures 54.6 × 13 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Traffic?

8 components, from 4 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 Traffic design files?

From the George-Emad31/Pcb 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 Traffic design in my own project?

The repository has no license, so all rights stay with George-Emad31. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Traffic 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.
