The PiRelay is a Raspberry Pi relay HAT that lets you control high-current and high-voltage devices directly from your Pi. Transform your home appliances into smart IoT devices with four independent relay channels capable of switching loads up to 240VAC/7A or 125VDC/10A.
The standardised HAT form factor connects smoothly to any 40-pin Raspberry Pi, with a stacking header that keeps GPIO pins accessible for additional boards. LED indicators show relay status at a glance for easy debugging.
