Hex: common questions

What microcontroller does the Hex use?

The Hex is built around the ATMEGA1284-A, from the AVR/Arduino family.

How big is the Hex PCB?

The Hex measures 49.5 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hex?

54 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hex design files?

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

Can I use the Hex design in my own project?

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

Can I test firmware for the Hex 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.
