Note
When carrying heavy Inductive load for a period of time, the on-board MCU might be down and a reset procedure is needed.
Tip
This product is fully compatible with Raspberry Pi 4 (1GB, 2GB,4GB) and hopes you enjoy hacking with Pi 4 and all of other Pi 4 accessories.
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.
