I2C address of Device

In some Arduino development projects or something like it, sometimes we forget what the I2C address of a device is. Therefore, to simplify this condition, in this article I collect List of device I2C addresses for the Arduino Project.

0x40 if A0 = 0, A1 =1
0x41 if A0 = 1, A1 =0
0x44 if A0 = 0, A1 =1
0x45 if A0 = 1, A1 =1

*0 = not connected, 1 connected

Time

ImageAddress
DS1307
DS1307 I2C Address Arduino
RTC : 0x68

AT24C32 EEPROM : 0x50
DS3231 RTC
DS3231 I2C Address Arduino
RTC : 0x68

AT24C32 EEPROM:
0x57 if jumper A0 = 0, A1 = 0, A2 = 0 (Default)
0x56 if jumper A0 = 1, A1 = 0, A2 = 0
0x55 if jumper A0 = 0, A1 = 1, A2 = 0
0x54 if jumper A0 = 1, A1 = 1, A2 = 0
0x53 if jumper A0 = 0, A1 = 0, A2 = 1
0x52 if jumper A0 = 1, A1 = 0, A2 = 1
0x51 if jumper A0 = 0, A1 = 1, A2 = 1
0x50 if jumper A0 = 1, A1 = 1, A2 = 1

*0 = not connected, 1 connected

I hope this article List of I2C device addresses for Arduino Projects was useful. If you find it helpful and if so, you may share this article with other people.
