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.
Display
| Image | Feature | Address |
|---|---|---|
OLED SSD1306 I2C | Monochrome LCD 128×64 px | 0x3C |
LCD 16×2 I2C | Monochrome LCD 16×2 | 0x27 |
LCD 20×4 I2C | Monochrome LCD 20×4 | 0x3F |
Sensor
| Image | Feature | Address |
|---|---|---|
MPU-6050 | Accelerometer Gyroscope | 0x68 if ADO = 0 0x69 if ADO = 1 |
MPU-9250 | Accelerometer Gyroscope Magnetometer | 0x68 if ADO = 0 0x69 if ADO = 1 AK8963 (Magnetometer) Address: – 0x0C |
INA219 | Current Voltage Power | 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
| Image | Address |
|---|---|
DS1307 | RTC : 0x68 AT24C32 EEPROM : 0x50 |
DS3231 RTC | 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.
