Seeed Studio XIAO EXHIBITION

The Seeed Studio XIAO series, named after the Chinese word for "small," comprises tiny development boards based on various hardware platforms of ESP32, SAMD21, RP2040, nRF52840, RP2350 and RA4M1, MG24. These fingernail-sized boards pack powerful capabilities into a compact form factor.

Our team together with the community, has create a rich collection of wikis, applications and documentation to make the use and development with ease. To make it more efficient for the whole community to locate these useful docs, we're wrapping them up in this page as an index for you to locate the one you're looking for quickly.

We can't do it without the love, contribution that we get from the community, and if you want to contribute to this vibrant ecosystem (to fill in the blanket parts), we welcome your own submissions of your unique dev to inspire others in the community too.
