XIAO ESP32S3 is a high-performance board powered by Expressif ESP32-S3R8 chip. With support for 2.4GHz WiFi and low-power Bluetooth BLE 5.0 dual-mode wireless communication, this board is perfect for high-performance, low-power IoT applications.
When connected with the U.FL antenna, the remote communication distance and reach up to 100m.
Equipped with a powerful Xtensa 32-bit LX7 dual-core processor running at up to 240MHz, 8MB PSRAM, and 8MB Flash, XIAO ESP32S3 is designed to handle multi demanding tasks with ease.
Additionally, XIAO ESP32S3 supports lithium battery charging management and allows for deep sleep mode with power consumption as low as 14μA. With 4 adjustable power modes, XIAO ESP32S3 can balance communication distance, data rate, and power consumption to meet the needs of various application scenarios.
At just 21 x 17.5mm, XIAO ESP32S3 is designed with the classic thumb-sized form factor, making it perfect for wearable devices. Its breadboard-friendly and surface-mount design makes it ideal for production, with all SMD components on a single-sided board for ease of mass production.
