The Xiao ESP32-C3 by Seeed Studio is a compact yet remarkably powerful microcontroller designed to bring cutting-edge wireless capabilities to your smallest projects. Measuring just 0.73 x 0.50 inches, this board is packed with features that make it an ideal choice for Internet of Things (IoT) applications, wearable tech, rapid prototyping, and more.

At its core is the ESP32-C3 chip, built on a 32-bit RISC-V single-core processor running at 160 MHz. It offers built-in Wi-Fi (2.4GHz) and Bluetooth 5.0 (BLE) for smooth, energy-efficient wireless communication. Whether you're building a remote sensor network, a smart wearable, or a connected home device, the Xiao ESP32-C3 gives you robust wireless performance without needing additional modules.

The board supports 11 digital I/O pins (including 4 analog inputs and PWM), I2C, SPI, UART, and native USB-C for both power and data. It’s fully compatible with Arduino, PlatformIO, MicroPython, and CircuitPython, making it highly accessible for developers of all skill levels. Whether you're writing code on the fly or integrating into a more advanced workflow, the Xiao ESP32-C3 fits right in.

One standout feature is its ultra-low power consumption, making it an excellent choice for battery-powered devices. The compact size also means it’s perfect for wearables, smart textiles, compact robots, or even hidden sensors embedded in walls, furniture, or enclosures.

And despite its small form factor, the Xiao ESP32-C3 doesn't compromise on build quality. It features a high-quality PCB, castellated edges for easy soldering or mounting, and clearly labeled pins for smooth integration into any circuit or custom PCB.

Whether you're a maker, a student, or a professional developer, the Xiao ESP32-C3 offers a combination of small size, wireless performance, and development flexibility that’s hard to beat.
