H9uno: common questions

What microcontroller does the H9uno use?

The H9uno is built around the ATMEGA32M1-AU, from the AVR/Arduino family.

How big is the H9uno PCB?

The H9uno measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the H9uno?

30 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the H9uno design files?

From the c3h9dx/h9uno repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the H9uno design in my own project?

The repository has no license, so all rights stay with c3h9dx. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the H9uno 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.
