The ShillehTek XIAO ESP32S3 is a compact, ready-to-use microcontroller with onboard WiFi and Bluetooth, built for makers who want fast, practical results. Pre-soldered and plug-and-play, the module measures just 21.5mm x 17.5mm, making it ideal for space-constrained or embedded projects. It supports Arduino IDE and multiple languages including C++, Python and MicroPython so you can work in the environment you prefer. The board balances capability and efficiency for IoT and DIY uses, with a 240 MHz 32-bit dual-core LX7 processor for responsive performance and a low-power design suitable for battery-powered applications. Standard interfaces such as UART, SPI, I2C and PWM simplify connecting sensors and peripherals, keeping integration straightforward for prototyping and deployment.
