1. Introduction

The Sonar8 module is used to send and receive ultra sonic sonar pulses using the SonarSR module. Up to 8 SonarSR's can be controlled by this module.

2. Programming

There is no programming specification for the Sonar1 RoboBrick yet.

3. Hardware

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

3.1 Circuit Schematic

The schematic for the Sonar1 RoboBrick is shown below:

The parts list kept in a separate file -- sonar8.ptl.

3.2 Printed Circuit Board
