Quad channel thermocouple Arduino shield based on the MAX31856 universal digital thermocouple interface IC. This is an exciting update of the MAX31855, with improvements in resolution (19 vs 14 bits), on-board temperature reference (6 vs 4 bits), and compensation (fully compensated vs nonlinear correction required). The MAX31856 is interfaced via 4-wire SPI with options for interrupt triggering. An LDO and a high-speed level shifter are included on ALL device pins to allow interfacing with to any Arduino - both 3.3V and 5.0V variants - without sacrificing device performance in any operating condition.

Additional connector options are available in addition to standard J, K, T, and screw terminal

Kit includes Arduino shield and header kit.
