    Handwriting recognition is a very hot field of research and development, and is amongst the popular ways that electronics are beginning to transform the way we interact in our lives. However, most people regard such technologies to be out of the reach of the common person. With the Arduino Handwriting Recognition Kit, you can now easily get your hands on the hardware resources to begin building your own transformative handwriting recognition solution!

    The kit is powered by the Wio Terminal, which is your perfect integrated platform for designing and prototyping TinyML applications. It is powered by the ARM Cortex-M4 ATSAMD51 and includes an extensive range of peripherals such as an LCD display, buttons, sensors, and wireless connectivity. Accompanied by two fast and accurate VL53L0X Time-of-Flight sensors, the Wio Terminal creates a 2D map of the handwriting surface to detect gestures and classify them on the edge with TinyML.

    TinyML is a popular and tremendously significant field involving machine learning models that are designed to run on ultra-small, ultra low power microcontrollers. By combining the Arduino Handwriting Recognition Kit with the Edge Impulse platform, you too can develop your own machine learning application and deploy it within minutes!
