2. INTRODUCTION

The Underwater Equipment for Physiological Monitoring Development Board aims at
helping research and development in diving technologies. It combines all the hardware
and software required for monitoring the diver

’s physiology underwater.

The UEPM Development Board is provided will all the accessories, documents and
sample code to start developing immediately.

This document describes the hardware components of the UEPM Development Board
as well as their associated sample code.
