Overview

The LM50HV evaluation module (EVM) features a single-pole-double-throw (SPDT) switch that allows users to connect a power supply through test points. The LM50HVEVM uses a MSP430F5528 microcontroller along with a USB interface to enable users to datalog results and interface with the LM50HV analog output. The EVM is separated into two sections: the microcontroller section and the sensor section. The sensor section can be separated from the microcontroller section. The sensor side of the EVM must be reconnected to the microcontroller side to operate the LM50HV in a high temperature environment. The EVM has a single-pole-double-throw switch to allow users to evaluate the LM50HV in systems that use a VDD higher than the default 3.3V.
