📄️ GPIO Introduction
Before we start learning, let's take a detailed look at the Walnut Pi's GPIO pins, i.e., the 40-pin GPIO header mentioned earlier. The Walnut Pi is already a great single-board computer, but the GPIO design makes it easier for users to perform various DIY electronic projects, giving you an experience similar to using a powerful microcontroller development board.
