Seeed Studio XIAO ESP32-S3 – Ultra-Compact Dual-Core WiFi + BLE 5.0 Development Board

The Seeed Studio XIAO ESP32-S3 is a compact development board built around the ESP32-S3 platform. It provides a combination of processing power, wireless connectivity, low-power operation, and peripheral interfaces in the small XIAO form factor.

The dual-core Xtensa LX7 processor, operating at up to 240MHz, makes the board suitable for applications ranging from basic sensor monitoring to more demanding embedded processing. Wireless connectivity through 2.4GHz WiFi and Bluetooth 5.0 BLE enables communication with networks, smartphones, computers, and other wireless devices.

Its integrated lithium battery charging capability makes the board convenient for portable projects. The compact PCB can be incorporated into wearable devices, small robots, wireless sensor nodes, smart-home equipment, and other embedded systems where PCB space is limited.
