Breakout board for the MAX31855K digital thermocouple interface IC. Measured temperature range is -270C-1372C with known thermal characteristics and output resolution of 0.25C. This sensor supports a larger operating range (specifically in the negative range) than its predecessors, the MAX6674 and MAX6675, though it is not pin-pin compatible. This board is interfaced with a 0.1" 1x5 pin header, has a vertical mini thermocouple connector and four mounting holes for standoffs and 4-40 screws.

Note: There is a typo in the silkscreen that can be seen in the pictures. Instead of 'MAX31855K' the boards are labeled as 'MAX31885K'. This does not affect functionality in any way.
