Avr basic sbc: common questions

What microcontroller does the Avr basic sbc use?

The Avr basic sbc is built around the ATmega1284P-P, from the AVR/Arduino family.

How big is the Avr basic sbc PCB?

The Avr basic sbc measures 94 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avr basic sbc?

32 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avr basic sbc design files?

From the bazsimarkus/avr-basic-sbc 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 basic sbc 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 basic sbc 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.
