This is the Revision A verion of the CompassDT1 RoboBrick. The status of this project is work in progress.

CompassDT1 Robobrick (Revision A)

Table of Contents

This document is also available in PDF format.

1. Introduction

The CompassDT1 RoboBrick is a RoboBrick that can be used to connect to a Devantech CMPS01 compass module. This compass uses two Philips KMZ10A megnetic field sensors to measure the direction accurate to 0-3599 (i.e. .01 degree accuracy.) Please note that the magnetic field inside a build can be off by 10's of degrees.

2. Programming

{To be written}

3. Hardware

The hardware consists of a circuit schematic and a printed circuit board.

3.1 Circuit Schematic

The schematic for the CompassDT1 RoboBrick is shown below:
