GBAHD Shield: common questions

What microcontroller does the GBAHD Shield use?

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

How big is the GBAHD Shield?

The GBAHD Shield measures 48.3 × 51.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GBAHD Shield?

34 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the GBAHD Shield design files?

From the gbaHD/GBAHD-Shield repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the GBAHD Shield design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the GBAHD 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.
