Description
The Waveshare RTC WatchDog HAT is specifically designed to enhance the reliability and timekeeping accuracy of your Raspberry Pi. This HAT incorporates a MAX705 monitoring circuit, providing essential watchdog functionality to automatically reset the Raspberry Pi in case of system unresponsiveness, ensuring continuous operation for critical applications.
Beyond its robust watchdog capabilities, the HAT features a high-precision DS3231 Real-Time Clock (RTC) chip. This integrated RTC maintains accurate time and date, even when the Raspberry Pi is powered off, thanks to its dedicated CR1220 backup battery holder. This is crucial for applications requiring precise timestamping or scheduled events without relying on network time servers.
The board also includes convenient features like watchdog output warning indicators, configurable reset pin selection, and standard Raspberry Pi 40PIN GPIO compatibility, making it a versatile and dependable add-on for a wide range of embedded projects.
