UNICON board: common questions

What microcontroller does the UNICON board use?

The UNICON board is built around the ATXMEGA64A1-A, from the AVR/Arduino family.

How big is the UNICON board?

The UNICON board measures 127 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UNICON board?

127 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the UNICON board design files?

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

Can I use the UNICON board design in my own project?

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

Can I test firmware for the UNICON board 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.
