Description
Specifications

Seeed Studio XIAO ESP32S3 Plus, powered by ESP32-S3's 240MHz Xtensa 32-bit LX7 dual-core processor, brings more SMD pins to the tiny versatile XIAO ESP32S3. While maintaining all the powerful features including WiFi and BLE 5.0 wireless connectivities, 2.4GHz Rod antenna, and ultra-low power consumption of 14μA in deep sleep mode with lithium battery charging management, the Plus variant features redesigned castellations and pad layout on the back, offering 9 additional GPIOs specifically for advanced Bluetooth projects requiring expanded I/Os via SMD board-to-board soldering. It's ideal for advanced IoT projects, Smart Homes, and professional wireless devices requiring extra I/O connectivity. XIAO ESP32S3 Plus additionally features an upgraded 16MB Flash memory for advanced applications.

Key features

High-Performance MCU: Dual-core ESP32-S3 at 240MHz, Arduino / MicroPython / ESP-IDF compatible
Advanced Wireless: 2.4GHz WiFi & BLE 5.0, 100m+ range with U.FL antenna support
Efficient Power Management: Four power modes with 14μA deep sleep, integrated Li-ion charging
Expanded 20 GPIOs: 9 extra 1.27mm pitch SMD castellation pins beyond standard XIAO nRF52840
Universal Compatibility: Standard backside layout (with aligned battery pads, and debugger pads) for more to-be-released XIAO expansion boards
Classic XIAO Form Factor: 21×17.8mm design with 2.54mm pin headers, single-sided mounting for wearables and space-constrained projects
