New I2C RTC DS1307 High Precision RTC Module Real Time Clock Module Compatible with Raspberry Pi clock module
Baby Description:
This module is specifically designed for raspberry RT module. The module uses I2C mode to communicate with raspberry. The onboard DS1307 clock chip and a 1220 button battery ensure that the raspberry can still remember the time after power is lost. Set aside the serial port, convenient way to debug TTL.
Baby features:
on board DS1307 chip;CR1220 button battery never power;Can be directly used shell script operation;
Lead raspberry to send a string to facilitate debugging;
Programmable square wave output.
Product Interface:Raspberry Pi B version 2X13 socket;
Raspberry Pi A + / B + / 2 generation 2X20 socket;Support raspberry to send B / A + / B + / 2;
2 * 5p 2.54mm pitch interface.
Product parameters:
Working voltage is 5V;
0 ° C to + 40 ° C range of ± 2ppm clock accuracy;The real-time clock provides seconds, minutes, hours, weeks, dates, months, and years of information, and provides leap year compensation valid for 2100 years;

6: More information:
The DS1307 is a low-cost, high-precision I2C real-time clock (RTC) that includes battery inputs that remain accurate when the mains supply is disconnected. The Ds1307 has long-term accuracy and reduces the number of components in the production line. The DS1307 offers a commercial and industrial temperature range in an 8-pin 64mil SO package with low power consumption and a static current consumption of less than 500nA in battery-powered standby.RTC saves seconds, minutes, hours, weeks, dates, months and years. Less than 31 days in the month, will automatically adjust the date of the end, including the leap year correction. The working format of the clock can be 24 hours or 12-hour format with / AM / PM indication. Provides two settable calendar alarms and a settable square wave output. The address and data are transmitted serially via I2C bi-directional bus.
Precise, temperature-compensated voltage reference and comparator circuits are used to monitor the VCC status, detect power failures, provide reset outputs, and automatically switch to backup power if necessary.
