Adafruit’s I2C Address Reference

Pt 1008
Adafruit’s I2C Address Reference – Here’s a handy little table, in case you want to have multiple I2C devices on one bus. We’re trying to document all the most popular sensors/devices and their I2C addresses.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Excellent idea!
    Here’s another one that I’ve been using:
    PCF8563 (RTC) – 0x51

  2. I needed this the other night. Just two I2C devices but of course they both happened to be using 0x68. Luckily the MCP3424 can be configured to use a different address.

    18 bit ADC
    MCP3422 0x68
    MCP3423 0x68-0x6F
    MCP3424 0x68-0x6F

    16 bit ADC
    MCP3426 0x68
    MCP3427 0x68-0x6F
    MCP3428 0x68-0x6F
