OPT3101 Evaluation Module
This user’s guide provides an overview of the OPT3101 time-of-flight (ToF) proximity sensor evaluation
module (EVM). The OPT3101EVM is a single-pixel implementation of the OPT3101 device consisting of a
printed-circuit board (PCB) and an accompanying software package. The EVM is intended for prototyping
and evaluation. This user’s guide includes an overview of the EVM hardware and software in addition to
the schematic diagram, layout, and bill of materials. Throughout this document, the abbreviation EVM and
the term evaluation module are synonymous with the OPT3101EVM.
