Description
The board uses the MAX31855K instead of the MAX6675, so it can measure a wider temperature measurement range. Please note! the MAX31855 is not pin compatible or drop-in code compatible with the MAX6675. We do have an Arduino library for both chips but you'll need to adjust any existing MAX6675 designs for the new MAX31855. The MAX6675 has been discontinued by Maxim.
Key features
- Works with any K type thermocouple
- Will not work with any other kind of thermocouple other than K type
- -200C to +1350C output in 0.25 degree increments - note that K thermocouples have about
- +-2°C to +-6°C accuracy
- Internal temperature reading
- 3.3 to 5v power supply and logic level compliant!
- SPI data output requires any 3 digital I/O pins.
