Seeed Studio for XIAO ESP32S3 Plus, powered by ESP32-S3's 240MHz Xtensa 32-bit LX7 dual-core processor, brings more SMD pins to the tiny versatile for 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. High-Performance MCU: Dual-core ESP32-S3 at 240MHz, for Arduino / for MicroPython / for 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 for XIAO nRF52840. Universal Compatibility: Standard backside layout (with aligned battery pads, and debugger pads) for more to-be-released for XIAO expansion boards. XIAO Accessory Add-ons Compatibility: Natively compatible with all the for XIAO accessory add-ons of expansion, connectivity modules (LoRa, CAN_Bus, RS-485), sensors (2-Mic Array, Vision AI, mmWave Motion, Environmental sensing), and actuators (ePaper display, LED Matrix, relay and more). The printing/appearance may vary from batch to batch, but it will not affect the use; the actual product may have color difference due to different light or display.
