VCC - This is the positive power and logic level pin. It can be
2.2-5.5VDC, so fine for use with 3 or 5V logic. Power VCC with whatever
logic level you plan to use on the i2c lines.
- GND - this is the ground power and logic reference pin.
- SCL - this is the I2C clock pin. There's a 10K pull-up already on the board, so connect this directly to the i2c master clock pin on your microcontroller
- SDA - this is the I2C data pin. There's a 10K pull-up already on the board, so connect this directly to the i2c master data pin on your microcontroller
Alert - This is the interrupt/alert pin from the TMP007. The
chip has some capability to 'alert' you if the chip temperature goes
above or below a set amount. This output can trigger to let you know. We don't have library support for this pin, so check the datasheet for more information.
- AD0 AD1 - These are the address select pins. Since you can only have one device with a given address on an i2c bus, there must be a way to adjust the address if you want to put more than one TMP on a shared i2c bus. The AD0/AD1 pins set the bottom three pins of the i2c address. There are 10K pull-down resistors on the board.
