Unit RTC

SKU:U126

Description

Unit RTC is a programmable real-time clock module that integrates the HYM8563 low-power CMOS real-time clock/calendar chip. It uses the I2C communication interface and features a fully enclosed shell that effectively protects the circuit, ensuring more stable operation. It is suitable for use as a system clock in various embedded devices and instruments.

Features

  • Supports reading and writing of seconds, minutes, hours, day of the week, day, month, and year.
  • 32.768kHz high-precision clock crystal oscillator, significantly reducing time error.
  • Low power consumption, powered by a button battery that can operate continuously for many years.
  • Includes a century flag.
  • I2C communication interface.

Includes

  • 1 x Unit RTC
  • 1 x HY2.0-4P Grove cable (20cm)

Applications

  • Clocks, alarms
  • Power-off time synchronization
