Datasheet

The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that
control the load of high current. Which means it could be a nice solution for
controlling devices that couldn’t be directly controlled by IIC bus. Standardized shield
form factor enables smoothly connection with the Raspberry Pi. The shield also has
four dynamic indicators show the on/off state of each relay.
