Description

Module with real time clock and backup battery (battery included). It allows you to read the time in hours, minutes, and seconds, date: month, day, year. It has 32 KB of EEPROM. The communication interface is an I2C bus(SDA and SCL), data update frequency is 1 Hz (1 second). It is the output of the temperature sensorDS18B20.

 

The product is compatible with Arduino

The connect system makes it easy available inthe GitHub libraryfor users ofArduino.

 

Connection

The supply voltage of5 Vis connected to the terminal marked with the same symbol. The I2C bus must be connected to the outputs SCL- clock line andSDA - data line. PinSQis the output of a rectangular signal with the selected frequency (see page 3of the documentation).GNDis the ground system.

       

Pin Description
SQ The output of the square wave signal.
DS The output of the temperature sensor DS18B20.
SCL Clock line of I2C interface.
SDA Data line of I2C interface.
VCC The supply voltage of 5 V.
GND The ground of the system.
BAT The battery output.

Connectors

Outputs are solder fields for soldering goldpin connectors- 2.54 mm raster (not included). Thanks to them, it is possible to connect the system with thebreakout boardor the main module (for example,STM32DiscoveryorArduino) viawires.

Question: Good day Does Index: GRL-12507 work with 3.3V supply ? I ask because w/ documentation there is a chance.
Answer: On page 9 of the documentation there is information about the recommended operating parameters of the module and the power supply is given in the range from 4.5 V to 5.54 V. We recommend a power supply within this range.

RPi Pico has no problem with communication, the only problem is the battery, which does not fully enter the basket (too tight)
