SirDuke: common questions
What microcontroller does the SirDuke use?
The SirDuke is built around the ATmega8-16AU, from the AVR/Arduino family.
How big is the SirDuke PCB?
The SirDuke measures 42.4 × 14.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SirDuke?
20 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the SirDuke design files?
From the vul-os/sirboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the SirDuke design in my own project?
Yes, under the terms of its Apache-2.0 license, which vul-os chose for the repository.
Can I test firmware for the SirDuke 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.
