Shield: common questions

What microcontroller does the Shield use?

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

How big is the Shield?

The Shield measures 52.7 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Shield?

57 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Shield design files?

From the ksmonkey123/moba3 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Shield design in my own project?

Yes, under the terms of its MIT license, which ksmonkey123 chose for the repository.

Can I test firmware for the Shield 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.
