Avr breadboard: common questions

What microcontroller does the Avr breadboard use?

The Avr breadboard is built around the ATtiny13-20PU, from the AVR/Arduino family.

How big is the Avr breadboard PCB?

The Avr breadboard measures 33.2 × 47.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avr breadboard?

10 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avr breadboard design files?

From the alejandrogallo/avr-breadboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Avr breadboard design in my own project?

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

Can I test firmware for the Avr breadboard 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.
