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

Flash: common questions
Where can I find a Flash reference design?
Each of the 4 boards on this page is a real design using the Flash. 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 Flash use?
Most are built on ESP32 (2), NXP (1) and RP2040/RP2350 (1).
How big is a typical board using the Flash?
The median is 81.6 × 48.3 mm, and 25% are two-layer designs.
What is the most popular open source board using the Flash?
By GitHub stars, Marmota by inputlabs, with 127 stars.
Can I simulate one of these boards using the Flash 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.
