The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI™-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as 1024°C, and exhibits thermocouple accuracy of 8LSBs for temperatures ranging from 0°C to 700°C. The MAX6675 is available in a small, 8-pin SO package.

It is an easily cascadable 8×8 monochromatic LED dot matrix display module with onboard MAXIM’s MAX7219 LED driver chip. The MAX7219 allows you to drive the LED matrix using only three I/O pins of Arduino or any other microcontroller. The LED matrix module used in Easy Matrix has a bigger dot size (5mm) and has the overall display dimensions of 60.2mm x 60.2mm (2.4″x2.4″). It is easily cascadable in series with the help of precisely aligned male and female header pairs located on the left and right sides of the display module. With lots of freely available Arduino libraries for MAX7219 chip, this module is easy to use in any Arduino project for displaying basic text and animation.
