Overview
The Single Relay Board can be used to turn lights, fans and other devices on/off while keeping them isolated from your microcontroller. The Single Relay Board allows you to control high-power devices (up to 10 A) via the on-board relay. Control of the relay is provided via a 1 x 3 header – friendly to servo cables and convenient to connect to many development boards.
Key Features:
-
Control high-power devices up to 10 A with a simple high/low signal
-
Provides isolation between the microcontroller and device being controlled
-
Screw terminals for relay connections
-
3-pin servo-style header for power/signal interface
-
LED indicator provides visual feedback
