GH-MXAlps mini: common questions

What microcontroller does the GH-MXAlps mini use?

The GH-MXAlps mini is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the GH-MXAlps mini PCB?

The GH-MXAlps mini measures 294.5 × 133.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GH-MXAlps mini?

106 components, from 99 distinct parts. The full bill of materials is listed on this page.

Where can I download the GH-MXAlps mini design files?

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

Can I use the GH-MXAlps mini design in my own project?

The repository has no license, so all rights stay with agodinhost. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the GH-MXAlps mini 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.
