Neige: common questions

What microcontroller does the Neige use?

The Neige is built around the STM32F072CBU6, from the STM32 family.

How big is the Neige PCB?

The Neige measures 257 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Neige?

92 components, from 18 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 Neige design files?

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

Can I use the Neige design in my own project?

Yes, under the terms of its MIT license, which ymkn chose for the repository.

Can I test firmware for the Neige 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.
