MainCircuit v2 top: common questions

What microcontroller does the MainCircuit v2 top use?

The MainCircuit v2 top is built around the STM32F446RE, from the STM32 family.

How big is the MainCircuit v2 top PCB?

The MainCircuit v2 top measures 91 × 33 mm, has 2 copper layers and is 1 mm thick.

How many components are on the MainCircuit v2 top?

84 components, from 31 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 MainCircuit v2 top design files?

From the shimotoriharuki/2019RoboTrace_Kicad repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MainCircuit v2 top design in my own project?

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

Can I test firmware for the MainCircuit v2 top 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.
