Super Watchdog V7 for Raspberry Pi

The Super Watchdog V7 is an efficient tool for safeguarding Raspberry Pi in all your projects.

It provides two key functions: power-cycling the Raspberry Pi during software lock-ups and preventing SD card failure during power loss.

The device has a default 120-second timer, cutting and restoring power if the Raspberry Pi doesn't issue a reset command. Compatible with Raspberry Pi models B+, 2, 3, 4, 5, and Zero, it uses minimal GPIO pins. The board supports various power connectors and can operate on a 18650 Li-Ion battery for continuous operation during power outages. Additionally, it features an onboard self-test for functionality assurance and a push-button for manual Raspberry Pi control.
