Product Description
The Seeed Studio XIAO ESP32C3 is a thumb-sized development board that redefines the standards of compact IoT engineering. Powered by the high-performance ESP32-C3 RISC-V chip, it integrates a full wireless ecosystem including WiFi and Bluetooth 5.0 in a footprint smaller than a postage stamp. All components are mounted on a single side, making it an ideal candidate for SMD soldering onto custom carrier boards. With its advanced power management and built-in battery charging circuitry, this board is specifically engineered for wearable technology, remote sensing nodes, and portable smart devices that demand maximum efficiency within restricted spaces.
Detailed Key Features
Postage-Stamp Form Factor: Measuring only 21mm x 17.5mm, it is designed for ultra-low profile applications such as smart wearables and hidden IoT sensors.
Modern RISC-V Core: Utilises an open-source RISC-V 32-bit processor, offering an exceptional performance-to-power ratio for sophisticated embedded tasks.
Autonomous Power Design: Features a dedicated onboard charging chip and battery soldering pads on the underside, enabling direct operation from a 3.7V LiPo battery.
Versatile Connectivity: Despite its miniature size, the board provides 11 digital I/O pins (all PWM capable) and 4 analogue inputs, supporting UART, I2C, and SPI protocols.
Enhanced Signal Range: Equipped with a detachable external U.FL (IPEX) antenna, providing significantly better signal stability and range compared to standard PCB antennas.
