Please advise and comment asap, thanks-juliet

Sorry it could not receive the External Signal.
The SQ pin is just to output the Square Wave in different frequency.
JaneYu From Specification section: "4KB ROM of EEPROM".
Does it mean this module additionally has memory available for user purposes to write/read any required data ?
JaneYu Yes, you could read/write data to the EEPROM.
Please refer to our Github.
We have written the API function of EEPROM.
Thanks for the reply, but would there be any difference in wiring? To my understanding, this module only works in 5v but the raspberry pi pin is working under 3.3v.
JaneYu Dear Robert
What is the diffrent between this (RTC V1.1) and https://www.dfrobot.com/wik...
JaneYu They're two versions, compare to version 1.0, version 1.1 has EEPROM, so it has more room to save data and it can change the I2C address
You mean you want to add a RTC module on the lattepanda? Actually, lattepanda comes within RTC module on the board. Just add a battery.

JaneYu Hi, DS pin is prepared for the DS18B20 temperature sensor, please ignore it.
