Feature:1. This module mainly uses the high-precision clock chip DS3234, low-cost, ultra-high-precision, real-time clock (RTC) using SPI bus, integrated temperature compensation crystal oscillator (TCXO) and crystal.
2. DS3234 also integrates a 256‑word SRAM with battery backup. When the main power supply is powered off, the contents of the memory can be maintained through the power supply connected to the V BAT pin.
3. The RTC module can count seconds, minutes, hours, days of the week, date, month and year information, and can work in a 24‑hour or 12‑hour format with /AM/PM indication.
4. For months with less than 31 days, the clock module can automatically adjust the date at the end of the month, with a leap year correction function.
5. The module provides 2 programmable timing alarm clocks and one programmable square wave output every day. Address and data are serially transmitted through the SPI bidirectional bus.
