This user's guide describes the characteristics, operation, and use of the
evaluation module (EVM). This EVM demonstrates the application of the
sensor for contactless angle measurement in rotary systems. The EVM implements both encoding and
decoding of absolute angle information. Throughout this document, the terms evaluation board, evaluation
module, and EVM are synonymous with the DRV5055-ANGLE-EVM. This document includes a schematic,
reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).
