NAV I: common questions

What microcontroller does the NAV I use?

The NAV I is built around the C118207, from the STM32 family.

How many components are on the NAV I?

92 components, from 56 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 NAV I design files?

From the Karteek-N/NAV_I repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the NAV I design in my own project?

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

Can I test firmware for the NAV I 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.
