PCB for mini SYM-1

If you are like me  I am not best at bread boarding circuits. From the mini board schematic diagram I have generated a pcb design and gerber files that you be able to make your own boards from. See link below.

Word of Caution First
I have not made any of these pcb's so make sure you check the board out before any component mounting. In case there is any major faults let me know. One mistake that I am aware of is that the polarized caps C5,7 and 8 show the "+" on the wrong side. So make sure you mount polarized caps the correct way around.
When I get time will try to correct that.

At this point I am only providing the full set of the gerber files from which you can get the boards manufactured. From more expensive pcb websites the board will work out about $30-$40 .. but if you shop around and get more than one board ..they will probably work out $10-15 each.

Top silk layout and component placement

Most of component placement is self explanatory. It is possible to power the board from TTL/USB connector (by getting +5 volts from PC USB port). But word of caution in doing that. The setup draws about 220mA, so make sure all the connection on J1 are solid. Also if you to use USB power then do not power the board from PWR/RST connector.
