Thermocouple Amplifier MAX31855 Breakout Board - v2.0

Thermocouple Amplifier MAX31855 Breakout Board - v2.0 info

Thermocouple Amplifier MAX31855 Breakout Board - v2.0 is a thermocouple amplifier breakout board based on MAXIM’s MAX31855K. 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).

Version 2.0 now includes ferrite beads and filter capacitor onboard for better stability
