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 idealfor advanced IoT projects, Smart Homes, and professional wireless devices requiring extra I/O connectivity.
Inspired by the unique SMD pins design of the RICK TNY, we're now introducing the Seeed Studio XIAO Plus boards (available in XIAO nRF52840 Plus, XIAO nRF52840 Sense Plus, and XIAO ESP32S3 Plus) to include an updated design of more castellations and a new pad layout on the back.
