Thermocouple Amplifier MAX31855 Breakout Board R2.0 for Raspberry Pi
Thermocouples are very sensitive£¬ requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you£¬ and can be easily interfaced with any microcontroller£¬ even one 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 or perfboard). Goes great with our 1m K-type thermocouple. 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. Works with any K type thermocouple Will not work with any other kind of thermocouple other than K type -200°C to +1350°C 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.
