Power Pins

  • Vin - this is the power pin. This chip can handle 2.7V to 5V. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V
  • GND - common ground for power and logic

I2C Logic Pins

Default I2C address is 0x67.

  • SCL - this is the I2C clock pin, connect to your microcontroller's I2C clock line.
  • SDA - this is the I2C data pin, connect to your microcontroller's I2C data line.

Alert Pins

  • A1 - A4 - Alert 1 - Alert 4 output pins

Address Pin

  • ADDR - Allows for setting I2C address.

Changing the I2C Address

By default, the ADDR pin is tied to Vin. This sets the default I2C address to 0x67. To change the I2C address, you can use the provided jumpers, or tie the ADDR pin directly to GND. This breakout supports a total of five I2C addresses, meaning you can connect up to five MCP9600 breakouts on the same I2C bus.

Use the following table to determine what to apply to the ADDR pin to get the desired address. The jumpers are numbered in the image. J1 applies to jumper 1, and J2 applies to jumper 2. An - in the table means no action needed, and an X in the table means to solder closed a jumper. The final address requires tying the ADDR pin to the GND pin, and in that case, all other changes are ignored.
