Atlas MCU Board: common questions
What microcontroller does the Atlas MCU Board use?
The Atlas MCU Board is built around the ATMEGA328P-AU, from the AVR/Arduino family.
How big is the Atlas MCU Board?
The Atlas MCU Board measures 57.1 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Atlas MCU Board?
35 components, from 23 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 Atlas MCU Board design files?
From the manpreet-singh/Atlas 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 Atlas MCU Board design in my own project?
Yes, under the terms of its GPL-3.0 license, which manpreet-singh chose for the repository.
Can I test firmware for the Atlas MCU Board 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.
