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.
