1. Introduction

The Sonar8 module is used to send and receive ultra sonic sonar pulses using the Robot Electronics SRF04 sonar ranging module. Up to 8 SRF04'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

The printed circuit board files are listed below:

sonar8_back.png: The solder side layer.
sonar8_front.png: The component side layer.
sonar8_artwork.png: The artwork layer.
sonar8.gbl: The RS-274X "Gerber" back (solder side) layer.
sonar8.gtl: The RS-274X "Gerber" top (component side) layer.
sonar8.gal: The RS-274X "Gerber" artwork layer.
sonar8.drl: The "Excellon" NC drill file.
sonar8.tol: The "Excellon" tool rack file.

4. Software

The Sonar8 software is available as one of:

sonar8.ucl: The µCL source file.
sonar8.asm: The resulting human readable PIC assembly file.
sonar8.lst: The resulting human readable PIC listing file.
sonar8.hex: The resulting Intel^® Hex file that can be fed into a PIC12C5xx programmer.

5. Issues
