Avr mod player: common questions

What microcontroller does the Avr mod player use?

The Avr mod player is built around the ATmega32A-P, from the AVR/Arduino family.

How big is the Avr mod player PCB?

The Avr mod player measures 100 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avr mod player?

46 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avr mod player design files?

From the bazsimarkus/avr-mod-player repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Avr mod player design in my own project?

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

Can I test firmware for the Avr mod player 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.
