Engineered with makers, engineers, and IoT developers in mind, the XIAO series supports popular development environments including Arduino IDE and MicroPython. Whether utilized in wearable tech, smart home sensors, or robotics, it provides a reliable and cost-effective foundation for embedding intelligence into physical spaces.

ESP32 DevKitC

The ESP32 DevKitC is a small-form-factor development board created by Espressif Systems, designed for prototyping and rapid application development in the Internet of Things space. It integrates a powerful ESP32 system-on-chip featuring dual-core processing, rich peripheral sets, and reliable wireless connectivity. Engineered with breadboard-friendly pinouts and a built-in USB-to-UART bridge, this board simplifies programming and debugging for both beginners and professional engineers. It serves as a foundational building block for smart home devices, industrial automation, and wireless sensor networks.

Arduino Uno R4

The Arduino Uno R4 is the latest revision of the world's most popular beginner microcontroller board, now powered by a 32-bit Renesas RA4M1 processor - a major jump from the original 8-bit design while keeping the same beginner-friendly form factor and pin layout. It remains the standard starting point for electronics education, supported by an enormous library ecosystem and the simple Arduino IDE, making it approachable for students and hobbyists building their first circuits. The WiFi variant adds built-in wireless connectivity for IoT projects, while a built-in 12x8 LED matrix on the WiFi model enables simple visual output without extra components.

NodeMCU (ESP8266)

The NodeMCU is an open‑source development board that integrates the ESP8266 Wi‑Fi SoC with a USB‑to‑serial converter and a convenient pin layout. It runs the Lua‑based NodeMCU firmware out of the box, allowing you to write scripts directly on the device without a separate compiler. Its small size, 3.3 V logic, and extensive community support make it ideal for hobbyists and engineers who need to add wireless connectivity to sensors, actuators, or small embedded projects quickly.

Teensy 4.1

The Teensy 4.1 is a powerful microcontroller board featuring an NXP i.MX RT1062 processor running at 600 MHz, providing exceptional computing power in a compact form factor. It includes expanded memory options with an onboard MicroSD card socket and room for optional Flash and PSRAM chips. Building on the success of its predecessor, the 4.1 retains the familiar breadboard-friendly layout while adding significantly more I/O pins, an Ethernet PHY, and a USB host port, making it ideal for advanced audio processing, robotics, and custom hardware controllers.

BBC micro:bit

The BBC micro:bit is a tiny, fully programmable microcontroller board designed for education and hobbyist projects. It features built‑in sensors, LEDs, and wireless connectivity, making it easy to create interactive prototypes without extra hardware.
