2-Ch Relay XBee BTBee Shield for Arduino
This SainSmart 2-Channel Relay Shield is designed to extend Arduino boards like the UNO, MEGA R3, Mega2560, and Due, enabling wireless control of relays. It features two onboard 5V relays capable of switching loads up to AC 250V 10A or DC 30V 10A. The shield offers easy integration with various wireless modules, including XBee, BTBee, nRFL2401, and CC1101. Furthermore, it expands connectivity with six electronic bricks ports and three servo motor ports, simplifying development for projects requiring both relay actuation and sensor/actuator interfacing. It operates on a standard 5V supply.
