Seeed Studio XIAO is a full ecosystem that offers compact, Arduino-compatible development boards with expandable accessories for sensors, actuators, and connectivity.
Three product families — core boards, expansion add-ons, and ready-to-use gadgets — one XIAO ecosystem.
Thumb-sized, Arduino-compatible microcontrollers powered by popular chipsets for TinyML and edge computing.
Narrow down XIAO boards by connectivity, platform, sensors, interfaces and purchase options.
