Product Details

The MAX31889 evaluation system (EV system) provides a single platform to evaluate the MAX31889, a temperature sensor with ±0.3°C accuracy. The EV system consists of two boards connected through headers, a MAX32630FTHR microcontroller board, and the MAX31889 EV kit board. The MAX32630FTHR contains the firmware necessary to use the PC GUI program and also provides power to the MAX31889 EV kit board. The MAX31889 EV kit board ships with jumpers preinstalled to allow quick evaluation of the MAX31889.
