While numerous development boards exist in the market, the Raspberry Pi stands as the go-to device for hobbyists and tinkerers. And why not? It's remarkably straightforward to connect a Raspberry Pi to an HDMI display, attach a keyboard and mouse, and voilà! You have a functional setup. When lacking a display, keyboard, and mouse, you can still remotely access the Raspberry Pi via SSH by connecting it over Ethernet or Wi-Fi. But what if you lack both Ethernet and Wi-Fi connections, rendering SSH inaccessible?

Fear not, for there is an alternative method to access the Raspberry Pi — the Serial Console. Utilizing the serial console also offers a way for users to view boot logs, providing insight into the boot-up process should users wish to tweak it. The serial console of the Raspberry Pi is accessible on the GPIO header, as depicted in the image below.
