The Raspberry Pi 3B+ builds on the Pi 3 architecture with higher clock speeds, dual-band Wi-Fi, Gigabit Ethernet (over USB 2.0), and better thermal management. It keeps the same 40-pin GPIO layout, but tightens up the hardware in ways that make it more reliable for connected and long-running projects. Pi 3B+ GPIO Pinout Pin Name … Read more
The Raspberry Pi 4 brings a major hardware upgrade with a faster Cortex-A72 CPU, LPDDR4 memory options up to 8GB, true Gigabit Ethernet, USB 3.0 ports, and dual 4K display support. It’s a significant step up in performance and I/O capability while keeping the same 40-pin GPIO layout. Pi 4 GPIO Pinout Pin Name / … Read more
The Raspberry Pi 5 keeps the same 40-pin GPIO header as previous models, so most existing accessories and projects still work. These pins let you connect sensors, modules, and other hardware directly to the board. Here’s the full pinout to help you get started with the Raspberry Pi 5’s GPIO. Official GPIO Pinout RPI 5 … Read more
