Whether you&rsquo;re controlling relays, reading sensors, driving motors, or blinking LEDs, your application needs a reliable way to talk to GPIO hardware. When that control needs to happen over a network — a web dashboard toggling lights, a monitoring system reading temperature sensors, or a test automation framework manipulating hardware — you need a GPIO server that exposes pins through a network-accessible API. Three Linux-based open-source frameworks — <strong>pigpiod</strong>, <strong>gpiozero</strong>, and <strong>libgpiod</strong> — each take a different approach to this challenge.</p>
