Texas Instruments TMAG5170, User Manual, Page: 3 / 22

3 Hardware
The EVM is an easy-to-use platform for evaluating the main features and performance of the TMAG5170. 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 it laid out for electromagnetic compatibility (EMC) testing. The EVM has both
sensitivity variations of the TMAG5170 installed, and may be broken into two separate boards as needed. It is
intended to interface with the
TI-SCB , but may be used stand-alone if desired.
3.1 Features
• Snap Apart PCB for evaluation of both TMAG5170A1 and TMAG5170A2 sensitivities
• GUI support to read and write device registers, as well as view and save measurement results
• 3D print rotate and push module
• Detachable EVM for custom use cases
• Conveniently powered from a common micro-USB connector
4 Operation
4.1 Quick Start Setup
The following instructions describe how to set up and use the EVM.
1. Download and install this driver: http://www.ti.com/lit/zip/sbac253
