5 open source boards using the CartBus
Real designs built with the CartBus, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

CartBus: common questions
Where can I find a CartBus reference design?
Each of the 5 boards on this page is a real design using the CartBus. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the CartBus?
The 74LVC1G332GW,125, AM29F016 and BA6129AF appear in the most repositories here.
Which microcontrollers do boards using the CartBus use?
Most are built on STM32 (1).
How big is a typical board using the CartBus?
The median is 51 × 60.7 mm, and 100% are two-layer designs.
What is the most popular open source board using the CartBus?
By GitHub stars, Mbc30flash by HDR, with 124 stars.
Can I simulate one of these boards using the CartBus before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
