Grove SPDT Relay - module with 30A relay

Your 5V system can wield great power with this big, beefy relay board. Kit contains all the parts you need to get your high-power load under control. Sparkfun KIT-13815

This industrial relay module, powered by the Raspberry Pi RP2350B microcontroller, features six 10A 250VAC/30VDC relays and an isolated RS485 interface. It ensures safe and stable operation thanks to opto-isolation, power isolation, and surge protection. It supports programming in C/C++, MicroPython, and the Arduino IDE, and the 40-pin Pico HAT connector allows for easy expansion. Its robust DIN housing and 7–36V DC power supply make it ideal for industrial automation and IoT projects. Waveshare RP2350-Relay-6CH
