Cobalt-X Zero: common questions

What microcontroller does the Cobalt-X Zero use?

The Cobalt-X Zero is built around the STM32G431KBT6, from the STM32 family.

How big is the Cobalt-X Zero PCB?

The Cobalt-X Zero measures 45.1 × 74.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cobalt-X Zero?

44 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 Cobalt-X Zero design files?

From the RealSynarix/Cobalt-X-Zero 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 Cobalt-X Zero design in my own project?

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

Can I test firmware for the Cobalt-X Zero 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.
