Tiny RTC DS***7 Shield V2.0 Without DS*8B*0 -Arduino Compatible
DS***7 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. DS***7 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 Ds***7 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 batteries (type CR***0), the positive upward:
Note: This shield whether including the battery or not depend on your country post office, because some of countries post office can not receive and ship item with battry according to the limit of postal service. So we will ship the battery with this item to some country and can not ship to other countries, thanks very much for your gentle understaind.
This tiny module embraces DS***7 time module and AT*4C*2 storage module. DS***7 and AT*4C*2 are connected to IIC bus.
Feature:
1, Power supply: 5V DC and Button Battery
2, Interface: IIC
3, Size: *6mm * *2mm * *3mm (Almost same size as CR***2 Button Battery)
4, Memory Capacity: *2K bit
5, IC: DS***7, AT*4C*2; DS***7 and AT*4C*2 can be used separately
6, Have the automatic adjustment function of second, minute, day, month and year
7, Take alarm output function and cut off power protection function
