DS1307 Real Time Clock Module with AT24C32 Memory, I2C, RoHS


DS1307 is a real-time chip of DALLAS company,which adopt I2C protocal to communicate with SCM, and there was this kind interface on Arduino, therefore is very convenient to link with each other. DS1307 have a programmable waveforms output, it can be used to drive LED lights, or trigger a certain event as a break off, but be careful when you use it to take some kind of high power module. We design the real clock module to pin out the I2C interface of Ds1307 and programmable waveforms output interface SQW are connected, but usually we will only use the I2C interface to realize basic set the clock/read function. Note, this module must be installed on the battery can work normally. The battery is button batteries (type CR2032).

Features:

  • Power supply: 5V DC and Button Battery
  • Interface: I2C
  • Size: 16mm * 22mm * 23mm (Almost same size as CR2032 Button Battery)
  • Memory Capacity : 32K bit
  • IC: DS1307, AT24C32.
  • Have the automatic adjustment function of second, minute, day, month and year
  • Take alarm output function and cut off power protection function
