BigBoi: common questions

What microcontroller does the BigBoi use?

The BigBoi is built around the STM32F469NIHx, from the STM32 family.

How big is the BigBoi PCB?

The BigBoi measures 70 × 70 mm, has 4 copper layers and is 1.61 mm thick.

How many components are on the BigBoi?

96 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the BigBoi design files?

From the NedreAkerselvSkapervOgAkadmikerforening/Nebula repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BigBoi design in my own project?

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

Can I test firmware for the BigBoi 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.
