6 open source boards using the SPI Flash
Real designs built with the SPI 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.

SPI Flash: common questions
Where can I find a SPI Flash reference design?
Each of the 6 boards on this page is a real design using the SPI 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.
What parts are used alongside the SPI Flash?
The Crystal Oscillator, ICE40UP5K-UWG30, LDO-X2SON-1.2V, LDO-X2SON-2.5V and LDO-X2SON-3.3V appear in the most repositories here.
Which microcontrollers do boards using the SPI Flash use?
Most are built on FPGA (2), RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the SPI Flash?
The median is 26.6 × 18.3 mm, and 50% are two-layer designs.
What is the most popular open source board using the SPI Flash?
By GitHub stars, Tomu, I'm by theacodes, with 1,143 stars.
Can I simulate one of these boards using the SPI 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.
