Raspberry Pi RTC Module SKU DFR0386

Introduction

The RTC module is specifically designed for Raspberry Pi. It communicated with Raspberry Pi through I2C bus. There is a Maxim DS1307 and CR1220 button cell on the board to keep the real time for a long time after the Raspberry Pi has it's powerdown. Set a serial port, TTL convenient way online debugging.

Specification=
• RTC module DS1307
• Battery model CR1220 button cell
• Opearting Voltage 5V
• I2C address 0x68
• Clock precision ±2ppm 0~40°C
• Unit information Second, Minute, Date, Week, Month and Year
• Two calendar clock
• Operating temperature
• Compatible with Raspberry Pi B/A+/B+/2B
• Interface 2*5p 2.54mm

HOW TO USE

Connection
• Connect the module to your Pi
• The module leads to the TX&RX pins, you could set the information via this port.

NOTE DO NOT power it again if the Raspberry Pi has been powered, or it will damage the module and Raspberry.

Test
• Input "sudo raspi-config" to Open Raspberry Pi I2C interface
• Select "Advanced Options"
• Select "I2C"
• Select "YES"
• Input "sudo vim.tiny /etc/modules" to add the module
• Add "i2c-dev" device
• Install I2C tools, input "sudo apt-get install i2c-tools"
• Input "sudo reboot" to reboot Raspberry Pi Input "sudo i2cdetect-y1" after a reboot. If everything goes well, the module will be detected normally.
• Input "sudo su--" to get "root" input "modprobe i2c-dev" to load I2C device.
• Input "echo "ds1307 0x68" to load to Raspberry Pi
system I2C device.
• Now you can use "hwclock" command to use this module, refer to "man hwclock" for more details. "hwclock -r" Get RTC module time "hwclock -w" Set system time
6-7-17
