Provides the ability to control antenna selections in a communication network using frequency data from a SDR Radio. Coding was simple and performance is excellent using an Arduino UNO. I can recommend this relay board for its excellent quality and performance.

Compact and effective relay shield
It is really compact effective relay module for controlling a 12 V linear actuator or a 12 V DC motor.
