MAX31865 Evaluation Kit
General Description
The MAX31865 evaluation kit (EV kit) provides the hard-
ware and software (graphical user interface) necessary
to evaluate the MAX31865 RTD-to-digital Converter. The
EV kit includes a MAX31865ATP+ installed as well as a
USB-to-SPI interface.
The USB-to-SPI master section of the EV kit can be used
to interact with the MAX31865 EV kit software and exer-
cise the device’s functionality.
EV Kit Contents
● Assembled circuit board including MAX31865ATP+
and USB-to-SPI circuitry
● Mini-USB cable
