3-Channel Relay HAT for Raspberry Pi, GPIO Relay Expansion Board, Supports 5A 250V AC / 30V DC Load, Opto-Isolated, Onboard LEDs, Compatible with Raspberry Pi 5/4/3/Zero for Home Automation

Overview This 3-Channel Relay HAT for Raspberry Pi is an ideal power control solution for users looking to integrate their Rasp-berry Pi with high voltage or high current devices. Whether youre building a smart home system, an automated irrigation setup, or an industrial control panel, this HAT provides the reliable switching and GPIO control you need. The board supports the standard 40PIN GPIO interface, making it fully compatible with Rasp-berry Pi 5, 4, 3, and Zero series boards. Each of the three onboard high-quality relays supports loads up to 5A at 250V AC or 30V DC, enabling your Rasp-berry Pi to switch appliances such as lights, fans, solenoids, or small motors.

For safety and stability, this Rasp-berry Pi relay expansion board features photo-coupling isolation, which helps protect the low-voltage Rasp-berry Pi circuitry from potential surges or noise coming from the high-voltage relay outputs. To make debugging and monitoring easier, each relay is equipped with a status indicator LED, clearly showing the ON/OFF state in real time. The board also includes relay control jumpers, allowing you to reassign relay control to custom GPIO pins instead of the defaultsgreat for complex projects or when avoiding pin conflicts. This 3-channel relay HAT comes with a set of development resources, including example codes in Python, wiringPi, shell scripts, WebIOPi, and bcm2835, helping both beginners and advanced makers start quickly and integrate easily.

If you are working on Rasp-berry Pi home automation, smart device control, or other IoT projects, this relay module is a compact, stable, and versatile choice to power up your ideas. Package Contents 1. 3-CH-Relay HAT x 1 2. RPi screws pack (2pcs) x 1
