What boards using the DIR9001 are built for
DIR9001: common questions
Where can I find a DIR9001 reference design?
Each of the 4 boards on this page is a real design using the DIR9001. 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 DIR9001 use?
Most are built on STM32 (3) and FPGA (1).
How big is a typical board using the DIR9001?
The median is 100 × 87 mm, and 75% are two-layer designs.
What is the most popular open source board using the DIR9001?
By GitHub stars, Asynchronous-SPDIF-Mixer by DADDesign-Projects, with 12 stars.
Can I simulate one of these boards using the DIR9001 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.
