Navidat: common questions

What microcontroller does the Navidat use?

The Navidat is built around the ATMEGA32U2-AU, from the AVR/Arduino family.

How big is the Navidat PCB?

The Navidat measures 56.2 × 99.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Navidat?

32 components, from 14 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 Navidat design files?

From the str-dst/Navidat repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Navidat design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Navidat 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.
