Dual MAX31856 thermocouple breakout board for 5V systems (MAX31855 upgrade)

Description

You are buying a
Dual Maxim MAX31856 breakout board for 5V systems
.  This board has 2 MAX31856's on it to read the temperature of 2 thermocouples.  The datasheet for MAX31856 can be found on Maxim's web site (sorry, eBay doesn't allow links).
The MAX31856 is the latest thermocouple IC from Maxim, and is significantly better than the MAX31855:
19-bit temperature resolution (MAX31855 is only 14-bit)
Handles all thermocouple types (K, J, N, R, S, T, E, and B)
Allows readings as high as +1800°C and as low as -210°C depending on thermocouple type
Line frequency filtering of 50Hz and 60Hz is included
Many configuration options, like number of samples to average, fault masking, fault triggering etc.
You also get 2 low-mass, highly responsive k-type thermocouple probe capable of measuring -50°C to 700°C (-58°F to 1292°F).
Library and example application for Arduino can be found on Github (look for engineertype's MAX31856)
Specifications:
2 x MAX31856MUD+ Thermocouple-to-digital converter
Measures -210°C to +1800°C with 19-bits of resolution
Three LEDs: one indicating power and the other 2 to indicate faults
DC-to-DC power converter to convert your 5V into 3.3V needed by the MAX31856
Built-in level shifters to translate between 5V (your controller) and 3.3V (used by the MAX31856)
Breadboard-friendly 8-pin 0.1" header and a 4-pin 0.1" header
0.2" (5.08mm) screw terminals for thermocouple probe wires
Two screw holes for mounting the board
Dimensions: 1.6" x 1.3" (40mm x 34mm)
Compatible with Arduino, PIC and other 5V microcontrollers
