Mad navigator: common questions

What microcontroller does the Mad navigator use?

The Mad navigator is built around the STM32F100RBTx, from the STM32 family.

How big is the Mad navigator PCB?

The Mad navigator measures 173.4 × 82.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mad navigator?

104 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mad navigator design files?

From the maddevsio/mad-navigator repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mad navigator design in my own project?

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

Can I test firmware for the Mad navigator without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
