Euclid36: common questions

What microcontroller does the Euclid36 use?

The Euclid36 is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Euclid36 PCB?

The Euclid36 measures 248.2 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Euclid36?

130 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Euclid36 design files?

From the sadekbaroudi/euclid36 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Euclid36 design in my own project?

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

Can I test firmware for the Euclid36 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.
