Static AD: common questions
What microcontroller does the Static AD use?
The Static AD is built around the ATMEGA328-P, from the AVR/Arduino family.
How big is the Static AD PCB?
The Static AD measures 223.8 × 108.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Static AD?
111 components, from 22 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 Static AD design files?
From the 0xCB-dev/0xCB-Static 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 Static AD design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Static AD 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.
