4 open source boards using the MICROSD
Real designs built with the MICROSD, 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.

What boards using the MICROSD are built for
MICROSD: common questions
Where can I find a MICROSD reference design?
Each of the 4 boards on this page is a real design using the MICROSD. 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 MICROSD use?
Most are built on STM32 (3) and AVR/Arduino (1).
How big is a typical board using the MICROSD?
The median is 85 × 61.7 mm, and 67% are two-layer designs.
What is the most popular open source board using the MICROSD?
By GitHub stars, TOAD by cuspaceflight, with 93 stars.
Can I simulate one of these boards using the MICROSD 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.
