THERMO Click is an accessory board in mikroBUS form factor. It features the MAX31855K thermocouple-to-digital converter as well as a PCC-SMP connector for K-type thermocouple probes. The MAX31855K measures a temperature range of between -270°C and 1372°C with a sensitivity of about 41uV/°C. It has a built-in 14-bit ADC converter. THERMO Click communicates with the target board via an SPI interface (read-only). The board is designed to use a 3.3V power supply only. It has a green LED which indicates if the board is powered.
Type-K thermocouple with glass braid insulation is used for precision measurements of high temperatures. The thermocouple itself can measure up to 480°C. It is 2 meters long and ends with a PCC-SMP connector which is compatible with the THERMO click board.
