Development boards: common questions

What microcontroller does the Development boards use?

The Development boards is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Development boards PCB?

The Development boards measures 21 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Development boards?

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

Where can I download the Development boards design files?

From the Coolbots7/development-boards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Development boards design in my own project?

The repository has no license, so all rights stay with Coolbots7. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Development boards 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.
