Breakout board for 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 microcontroller devices between 3.3V and 5V (all Arduinos, Raspberry PI, etc) without sacrificing device performance in any operating condition. This board is interfaced with a 0.1" 1x9 pin header and has four mounting holes for standoffs and 4-40 screws.

Additional connector options are available
