3 open source boards using the SD_SLOT
Real designs built with the SD_SLOT, 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.

Microcontrollers on boards using the SD_SLOT
SD_SLOT: common questions
Where can I find a SD_SLOT reference design?
Each of the 3 boards on this page is a real design using the SD_SLOT. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the SD_SLOT use?
Most are built on STM32 (3).
How big is a typical board using the SD_SLOT?
The median is 91 × 33 mm, and 100% are two-layer designs.
What is the most popular open source board using the SD_SLOT?
By GitHub stars, MainCircuit v1 by shimotoriharuki, with 0 stars.
Can I simulate one of these boards using the SD_SLOT 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.
