The 4-Channel SPDT Relay HAT for Raspberry Pi utilizes four high-quality SPDT (single pole - double throw) relays and provides NO/NC (Normally Open/ Normally Closed) interfaces that can control the load of high current.

This is a great solution for controlling devices that can't be directly controlled by the I2C bus. The standardized shield form factor enables smooth connection with a Raspberry Pi and it also has four LED indicators that show the on/off state of each relay.
