Performance characteristics:
Open the original design of the circuit diagram, develop a software interface for free download, and make modifications according to your needs. The download program is simple and convenient. You can easily use sensors and various electronic components (such as LED lights, buzzers, buttons, photoresistors, etc.) to create a variety of interesting works:
Using a high-speed microprocessor controller (ATMEGA328), the development interface and environment are very simple and easy to understand, making it very suitable for beginners to learn.
