Description: This is an evaluation board for the MLX90614 IR Thermometer. The sensor is connected to an ATmega328 running at 3.3V with a STK500 (Arduino) 8MHz bootloader. Code can be loaded through the FTDI basic interface and the Arduino environment.
The MLX9061 sensor is a high precision, small size, single zone IR thermometer with an optional SMBus (two-wire) or PWM interface. The ATMega328 comes with demo code that gives a temperature readout in degrees F at 38400bps. You can use a 3.3V FTDI Basic to connect to the board.
This revision corrects the silkscreen error on the FTDI header. We’ve also added pull-up resistors to the I2C lines.

I bought this evaluation board to play around with while I had a few days off from work. I also bought the Micro OLED display, as shown in the hookup guide. There was very little information on how to actually get the OLED interfaced with this board, but I managed to figure it out after a few false starts. With the OLED connected and a Lipo battery as a power supply, I found myself checking the temperature on all sorts of things. How hot is my soup? What is the temperature of that window? How hot is that heat Sink? Anyway, kind of fun, much more so with the OLED display, and even a tad bit useful to boot.
