Microcontrollers on boards using the xiao
What boards using the xiao are built for
xiao: common questions
Where can I find a xiao reference design?
Each of the 3 boards on this page is a real design using the xiao. 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 xiao use?
Most are built on Nordic nRF (1) and RP2040/RP2350 (1).
How big is a typical board using the xiao?
The median is 95.5 × 73 mm, and 67% are two-layer designs.
What is the most popular open source board using the xiao?
By GitHub stars, Xiao kb01 by sago35, with 118 stars.
Can I simulate one of these boards using the xiao 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.
