The LMT01EVM allows users to evaluate the performance of the LMT01 2-pin digital temperature sensor.
The EVM comes in a USB stick form factor package with an onboard MSP430F5528 microcontroller that
interfaces with both the host computer and the LMT01 device. The EVM also comes with perforation at
two locations on the EVM board. The first perforation allows the user to connect wires, cable, or header to
both ends for remote temperature measurements. The second perforation allows the user to remove the
level shifter transistor (Q1) from the EVM board.
