Corevus toolboard: common questions

What microcontroller does the Corevus toolboard use?

The Corevus toolboard is built around the STM32G431KBU3, from the STM32 family.

How big is the Corevus toolboard PCB?

The Corevus toolboard measures 49.8 × 25.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Corevus toolboard?

81 components, from 53 distinct parts. The full bill of materials is listed on this page.

Where can I download the Corevus toolboard design files?

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

Can I use the Corevus toolboard design in my own project?

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

Can I test firmware for the Corevus toolboard 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.
