RPI Relay Board Hat


Categories: ,


The RPi Relay Board HAT is an expansion board made for automation and convenience, and is designed to fit Raspberry Pi Boards to allow for isolated operations of electrical circuits. It uses HLS8L relays to offer control over three different circuits, either for operating Electronics from a distance or for safely operating high voltages and currents.

In conjunction with a Raspberry Pi board, this Pi HAT can connect to the internet, use local WiFi, or even be connected to a timer or alarm so that you can automate projects, activate or deactivate them via an online portal, or protect yourself from high currents and voltages when dealing with high power circuitry. It mounts onto the top of a Raspberry Pi, with 40 pins that plug directly into the board, with a clean layout that makes it easy to understand and identify how each components works together.
