Adafruit MCP9601 (MCP96L01) I2C Thermocouple Amplifier

Post by bjmcontrols »

Does each board have a unique I2C address? I need to put eight of them on a bus and I need to be sure there are no duplicate addresses.

Thanks

According to this https://learn.adafruit.com/adafruit-mcp9601#pinouts
ADDR - The MCP9601 supports 8 addresses, ranging from 0x60 to 0x67. The default is 0x67, with the ADDR pin not connected to anything. To get 0x60, connect the ADDR pin directly to GND. To get the addresses between 0x60 and 0x67, you must add a resistor of a given value between ADDR and GND - check out Table 6-2 in the datasheet for a list of suggested resistor values for each address.
Addr jumpers - There are two jumpers on the back, labeled 43k and 22k, each of which change the I2C address. If you solder the 43k jumper closed, the address will be 0x66. If you solder the 22k jumper closed, the address will be 0x65.
