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 ESP32-S3 Plus) to include an updated design of more castellations and a new pad layout on the back.

Seeed Studio XIAO ESP32-S3 Plus, powered by ESP32-S3’s 240MHz Xtensa 32-bit LX7 dual-core processor, brings more SMD pins to the tiny versatile XIAO ESP32-S3. 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 ESP32-S3 Plus additionally features an upgraded 16MB Flash memory for advanced applications.

 

  • 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 x 17.8mm design with 2.54mm pin headers, single-sided mounting for wearables and space-constrained projects
  • XIAO Accessory Add-ons Compatibility: Natively compatible with all the 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).

Production-Ready Design with Fusion PCBA Support

As a new addition to the Seeed Studio XIAO family, the XIAO ESP32S3 Plus remains the classic XIAO design (thumb-size, SMD, stamp holes). All these features make it a perfect fit for either space-limited applications, or a production-ready System on Module (SoM) for your PCBA designs. With our Seeed Studio Fusion services, you can access competitive one-stop PCBA manufacturing, component sourcing, and testing, plus free DFA/DFM review to reduce manufacturing risks and accelerate the journey from prototype to production.
