M5Stack RTC Real Time Clock Unit HYM8563

The RTC Unit from M5Stack is a programmable real-time clock module featuring an integrated HYM8563 low-power CMOS real-time clock and an I2C communication interface. The RTC is housed in a sturdy plastic casing. Most MCUs come with built-in timers that are typically activated automatically when the hardware is powered on and reset when the hardware is turned off. The built-in timer can handle some simple timing tasks. If you want to implement timestamp recording, a clock, an alarm, and other time functions, a system-independent RTC is the best choice. The RTC Unit also includes an internal backup battery, ensuring that time is not lost during a power interruption.

Features of the RTC Unit:

• Supports reading and writing time data (second/minute/hour/day/month/year)
• High-precision 32.768kHz quartz that significantly reduces time error
• Low power consumption
• With the CR1220 backup battery, time is preserved for years
• Century mark support
• I2C communication interface
