Christmas board: common questions

What microcontroller does the Christmas board use?

The Christmas board is built around the ProMicro, from the AVR/Arduino family.

How big is the Christmas board?

The Christmas board measures 93.7 × 129.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Christmas board?

20 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Christmas board design files?

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

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

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

Can I test firmware for the Christmas 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.
