M5Stack U126 UNIT Real Time Clock (RTC)

m5Stack U126 UNIT Real-Time Clock (RTC) is a programmable real-time clock module, integrated HYM8563 low-power CMOS real-time clock/calendar chip. The device uses an I²C communication interface and has a full-coverage case that can effectively protect the circuit, making its operation more stable. Applicable to a variety of embedded devices, instruments, and instruments as a system clock.

Most MCUs are built-in timers, which usually start working automatically when the hardware is powered on and reset when the hardware is powered off. The m5Stack U126 UNIT RTC can handle some simple timing tasks. If the user wants to implement data timestamp recording, alarm clock, and other time-span functions, a system power-independent clock RTC is a great choice.
