The EVM is an easy-to-use platform for evaluating the main features and performance of the TMAG5170D.
The EVM includes a graphical user interface (GUI) used to read and write registers, as well as view and save
measurement results. Also included is a 3D-printed Rotate & Push module to test the common functions of angle
measurement and push button with a single device.
The EVM is intended to provide basic functional evaluation of the devices. The layout is not intended to be a
model for the target circuit, nor is the model laid out for electromagnetic compatibility (EMC) testing. The EVM
has both sensitivity variations of the TMAG5170D installed, and may be broken into two separate boards as
needed. The EVM is intended to interface with the TI-SCB, but may be used as a stand-alone device if desired.
