Thermocouples are very sensitive, requiring a good amplifier with a cold-junction compensation reference.
This product does everything for you, and can be easily interfaced with any microcontroller, even without an analog input.
This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested.
Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard).

Package Contents:
1 x Thermocouple Breakout Board
Note:
Works with any K type thermocouple
K thermocouples have about +/- 2°C to +/- 6°C accuracy
Internal temperature reading
3 to 5v power supply and logic level compliant!
SPI data output requires any 3 digital I/O pins.

Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
