maxtc - Breakout board for Maxim SPI thermocouple sensors
The Maxim MAX6675 and the newer MAX31855 thermocouple to SPI interface chips are very popular with electronics enthusiasts because of their extreme ease of use combined with good accuracy.
Both devices however are only available in SMD package making breadboard prototyping very difficult without using a suitable breakout PCB. Standard thermocouple connectors are also not breadboard friendly further aggravating the issue.
