ARDUINO Shield 4 Relays

The Arduino 4 Relays Shield is an open-source hardware expansion module designed to add four relay outputs to your Arduino projects. It features two TinkerKit inputs (IN2 and IN3) connected to analog pins A2 and A3, and two TinkerKit outputs (OUT5 and OUT6) routed to PWM pins 5 and 6, allowing flexible input and output configurations.

Additionally, the shield includes two 4-pin TinkerKit TWI connectors that share the same TWI interface, enabling you to chain multiple TWI devices seamlessly. This shield does not require external power as it draws power directly from the Arduino base board through the 5V and 3.3V pins.

Its compact dimensions (53 x 68.5 mm) and lightweight design (44g) make it an ideal choice for various development projects. Compatible with Arduino platforms, this shield is perfect for users looking to control multiple relays efficiently while maintaining easy integration with other TinkerKit components.

Whether you're building home automation systems, robotics, or other electronic projects, the Arduino 4 Relays Shield provides a reliable and versatile solution for expanding your Arduino capabilities.
