The MAX31856 evaluation system (EV system) provides the hardware and software necessary to evaluate the MAX31856 thermocouple-to-digital converter. The EV system includes the MAX31856PMB1 peripheral module with a PmodTM-compatible connector for SPI communication. The USB2PMB module provides the USB-to-SPI interface for communication with the software and it also provides USB power to the Pmod. The system also includes a K-type thermocouple for temperature sensing. Other thermocouple types (J, N, R, S, T, E, and B) can be evaluated with a user-supplied thermocouple.
