Pinouts
There is no difference between the breakout for the 55°x35° field of view and the 110°x70° field of view thermal
cameras. There is also no difference in the code used with either thermal camera. The only difference is the length of
the lens. The only way to tell which thermal camera breakout you have is to identify the length of the lens. The longer
lens, shown above on the left, is on the 55°x35° field of view thermal camera and is approximately 11.25mm long. The
shorter lens, shown above on the right, is on the 110°x70° field of view thermal camera and is approximately 5.7mm
long.
Power Pins
VIN - this is the power pin. Since the sensor chip uses 3 VDC, we have included a voltage regulator on board that
will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of
your microcontroller - e.g. for a 5V microcontroller like Arduino, use 5V
3V - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like
