Description

Seeed Studio Expansion Board for XIAO with Grove OLED – I2C, UART & GPIO

The Seeed Studio Expansion Board for XIAO with Grove OLED is a compact and feature-rich expansion board designed to make prototyping with Seeed Studio XIAO development boards easier and more versatile. It combines a 0.96-inch OLED display, Grove I2C, UART, and Analog/Digital interfaces, RTC, MicroSD card expansion, passive buzzer, user button, reset button, and SWD debugging in a compact form factor.

The onboard OLED allows users to display sensor data and debugging information directly, while the Grove connectors provide convenient plug-and-play connections to compatible sensors and modules. With battery support and CircuitPython compatibility, this XIAO expansion board is well suited for IoT devices, portable electronics, sensor monitoring, embedded applications, and rapid prototyping.

Features:

  • Rapid Prototyping Made Simple — Debug and reset your projects effortlessly with a dedicated RESET button and SWD pins routed to a male header. The built-in 0.96" OLED display lets you view data visually on the board itself — no need to rely on a PC serial monitor.
  • Packed with Peripherals — This board comes loaded with an OLED display, real-time clock (RTC), expandable storage, passive buzzer, user button, onboard battery management chip, and more. It's a single, all-in-one board designed to help you explore the full potential of the Seeed Studio XIAO series (excluding the XIAO nRF54 and MG24 series).
  • Ultra-Compact Design — Measuring just half the size of a Raspberry Pi 4, this sleek and compact board is ideal for space-constrained and wearable projects.
  • Solder-Free Setup — Every pin is broken out and ready to use. Convenient plug-and-play Grove connectors support multiple communication protocols, including I²C, UART, and Analog/Digital I/O.
  • CircuitPython Compatible — Fully supported by CircuitPython. A built-in MicroSD card slot allows you to expand storage, giving you the room to load additional libraries for prototyping and project development.
  • OLED Display — View data directly on the board without connecting to a PC. This makes debugging faster and opens the door to applications like sensor hubs, data dashboards, and more.
  • RESET Button — Reset your board with a single click — no more fumbling with jumper wires or risking short circuits.
  • SWD Debug Interface — SWD pins are exposed via a male header, simplifying debugger connections and firmware flashing.
  • High-Precision RTC — A real-time clock with battery backup keeps accurate time even when main power is disconnected.
  • Expandable Storage — A MicroSD card slot on the back eliminates memory constraints, making it easy to add libraries and run CircuitPython projects.
  • User Button — In addition to the RESET button, a separate user-programmable button is included for custom functionality.
  • Passive Buzzer — The same passive buzzer found on the Wio Terminal. Adjust the PWM frequency to produce different tones and even play buzzer-based melodies.
  • Grove Connectors — All pins are broken out through plug-and-play Grove connectors supporting standard protocols: Grove I²C ×2, Grove UART ×1, and Grove Analog/Digital (A0/D0) ×1.
  • LiPo Battery Charging — Features a standard JST 2.0mm LiPo battery connector with an integrated battery management system. Supports both USB and LiPo power, with convenient onboard charging.
  • 5V Servo Connector — A 5V output is routed to a male header, providing a ready-to-use connection point for 5V servos and sensors.
