Overview

Product Overview

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.

Questions & answers

Frequently asked questions

Yes. This development board supports Arduino IDE and can be programmed with C++, Python, or MicroPython. It is based on the ESP32-S3 platform and includes onboard WiFi and Bluetooth for connected projects.
The board comes pre-soldered, so the headers are already installed for breadboard and jumper-wire use. That saves setup time and avoids needing soldering tools before starting basic prototyping or testing.
It provides standard microcontroller interfaces including UART, SPI, I2C, and PWM. These let you connect common sensors, displays, modules, and other peripherals without relying only on one communication method.
Its compact 21.5mm x 17.5mm size, onboard WiFi and Bluetooth, and low-power design make it useful for embedded IoT projects, portable sensors, wireless controllers, and space-constrained DIY builds.
Choose this board if you want a compact ESP32-S3 development board with wireless connectivity and pre-soldered headers. For troubleshooting, confirm your Arduino IDE or MicroPython setup targets the ESP32-S3/XIAO board family and that wiring matches the selected interface.
