Microcontroller: common questions

What microcontroller does the Microcontroller use?

The Microcontroller is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Microcontroller PCB?

The Microcontroller measures 54.6 × 20.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Microcontroller?

25 components, from 17 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 Microcontroller 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 Microcontroller 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 Microcontroller 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.
