V2 0: common questions

What microcontroller does the V2 0 use?

The V2 0 is built around the STM32F40X_LQFP64, from the STM32 family.

How big is the V2 0 PCB?

The V2 0 measures 85 × 68 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the V2 0?

88 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the V2 0 design files?

From the svenssonjoel/FMRC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the V2 0 design in my own project?

Yes, under the terms of its GPL-3.0 license, which svenssonjoel chose for the repository.

Can I test firmware for the V2 0 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.
