Note
When carrying a heavy Inductive load for a long period of time, the on-board MCU might be down and a reset procedure is needed.
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 means it could be a nice 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.
