Seeeduino XIAO Expansion Board case

📦 Seeeduino XIAO Expansion Board — 3D Model

This is a 3D model of the Seeeduino XIAO Expansion Board, a compact and powerful expansion base designed for the Seeeduino XIAO series of microcontrollers. Ideal for prototyping, tinkering, and small embedded projects, this board greatly expands the functionality of your XIAO with built-in peripherals and easy-to-use interfaces.

🔹 Features include:
• Integrated 0.96″ OLED display for on-board visual output and data debugging. 
• Real-Time Clock (RTC) with battery backup for timekeeping in portable projects. 
• MicroSD card slot for expandable storage — perfect for file logging and extra libraries. 
• Passive buzzer and user button for simple audio feedback and interactions. 
• SWD debug pins and RESET button for easy development and firmware updates. 
• Grove connectors with support for I²C, UART, analog, and digital interfaces — no soldering required. 
• On-board LiPo battery management (charging and power) and a 5 V servo connector.

🧰 Why this board is great:
• Compact and elegant — roughly half the size of a Raspberry Pi 4 — making it perfect for tiny, wearable, and portable builds. 
• Supports CircuitPython as well as Arduino development environments, making it versatile for many users. 
• Plug-and-play design with all pins broken out and easy connection to external modules.

Whether you’re creating a sensor hub, data logger, or wearable gadget, this expansion board adds visual interface, power options, and a suite of peripherals to your Seeeduino XIAO — all in a compact footprint.
