Altimeter

This is the pcboard image exported from pcb.

Before sending the board off to be made, I printed out a board and did a test fit of all the parts.

I got the board back and assembled it using solder paste, heating the board, paste and parts up on an electric grill. This technique is described in a Spark Fun Tutorial

RS-232 Level Converter

I want to talk to the altimeter over a serial port (some day USB), but I don't plan to fly the RS232 level shifter. This board is a simple level shifter that plugs in to a connector on the altimeter.

Layout Files

This is what you're here for, right? Here is the PCB layout file: Alt7.pcb

Tool Info

I convert the gschem schematics to a PCB file using gsch2pcb. I extract a list of parts from the schematics as well. I put these commands into a Makefile: 

Alt7.pcb:       Alt7-1.schem Alt7-2.schem Alt7.parts
        gsch2pcb -d ~/gEDA/footprints Alt7.proj

Alt7.parts:     Alt7-1.schem Alt7-2.schem
        gnetlist -g partslist3 Alt7-?.schem -o Alt7.parts

The Alt7.proj file contains: 

schematics Alt7-1.schem Alt7-2.schem
output-name Alt7
