Hall-Hinge-EVM

ABSTRACT

This user's guide describes the characteristics, operation, and use of the HALL-HINGE Evaluation Module 
(EVM). This EVM is designed with accompany 

3D printed structures

 and magnet to evaluate TMAG5231B1 in a 

hinge lid closure apparatus used commonly in laptop lid closures and other lid and door detection applications. 
The design is compatible with the 

HALL-ADAPTER-EVM

 to allow broader testing of TI's magnetic sensing 

portfolio. This document includes a 

schematic

reference printed circuit board (PCB) layout

, and a 

complete bill 

of materials (BOM)

.
