The Seeed XIAO ESP32S3 Plus is a compact development board based on the ESP32-S3 dual-core processor running at 240MHz. It builds on the XIAO ESP32S3 platform by offering additional SMD castellations and rear pads, bringing the total to 20 GPIOs for expanded connectivity in space-limited projects.
The board features integrated 2.4GHz Wi-Fi and Bluetooth 5.0, ultra-low power consumption with 14μA deep sleep, USB-C for power and programming, and lithium battery charging management. With 8MB PSRAM and upgraded 16MB Flash memory on this Plus model, it is well suited for wireless IoT devices, edge AI applications, and advanced Bluetooth projects requiring multiple I/O connections.
Please note that Seeed XIAO Plus boards don’t come with pin headers as it’s designed for SMD board-to-board soldering, however we sell a set of XIAO headers in the store if you need them.
