SEEED STUDIO Relay Shield v3.0 for Arduino

The SEEED STUDIO Relay Shield v3.0 provides four high-quality relays, enabling Arduino and Seeeduino boards to control high current loads with ease. This versatile shield features on-board normally open (NO) and normally closed (NC) interfaces, offering an effective solution for controlling devices that cannot be directly managed by the Arduino's standard Digital I/Os.

Designed with a standardised shield form factor, it ensures a smooth and seamless connection with Arduino and compatible boards. For enhanced usability, the shield is equipped with four individual LED working status indicators, allowing users to clearly monitor the on/off state of each relay at a glance.

Connectivity is made simple and secure with relay screw terminals for reliable wiring. The board also features updated pins, including SCL, SDA, IOREF, and NC, expanding its integration capabilities. While it is directly compatible with Arduino Uno, Leonardo, and Seeeduino boards, it can also be used with other microcontrollers by utilising jumper cables.

With compact dimensions of 43 mm in height, 33 mm in width, and 15 mm in depth, and weighing just 80 grams, this relay shield is perfectly suited for space-constrained embedded projects.
