EKG DEVICE DISCLAIMER

IEC601 is a standard that specifies tests and requirements that medical devices must pass before they can be used on humans. However, none of the devices built from these designs have been tested according to these guidelines because of the costs involved. Therefore, a device based on any of these designs may not be used for medical purposes as no medical claims are made.

NOTE THAT CONNECTING A DEVICE VIA ELECTRODES TO HUMANS OR ANIMALS IS POTENTIALLY HAZARDOUS AND MAY RESULT IN ELECTRIC SHOCK AND/OR SEIZURE.

SECTION 1 OVERVIEW

Thank you for choosing the SHIELD-EKG-EMG prototype board from Olimex! This document provides a User’s Guide for the Olimex SHIELD-EKG-EMG. As an overview, this chapter gives the scope of this document and lists the board’s features. The document’s organization is then detailed.

1.1 Scope

The SHIELD-EKG-EMG is an extension module for Olimex's ARDUINO compatible boards – like OLIMEXINO-328, OLIMEXINO-STM32 and PIC32-PINGUINO, among others. The shield is also compatible with ARDUINO boards including ARDUINO UNO. The board comes with mounted connectors on it.

1.2 Features

 Stackable shield (pass-through headers) - up to 6 shields forming 6 channels; mounted

on top of each other and wired to A0-A6 analogue inputs

 Open hardware, open software project – user have access to all design documents  Calibration signal generation by D4/D9 digital output  Precise trimmer potentiometer for calibration (all boards are shipped completely as-

sembled, tested and calibrated so you should not do this unless you wat to see how things work)

 Input connector for passive or active electrodes  Works with both 3.3V and 5V Arduino boards  Available examples for Arduino, Pinguino and Maple
