The next step in creating the I/O interface for the VHF COMM radio heads is to create the PCB. I try to make the PCBs as much multi-function as possible so that they will fit a number of different devices that I use for the Lockheed L-1011 project.
When you click on the image above, you will see that I decided on a two layer (TOP/BOTTOM) design. The BOTTOM layer has a few outward facing components such as the MULTI PURPOSE POWER CONNECTOR (MPPC) and the USB connector. There is also a jumper that enables the board (can be coupled with a fake circuit breaker on the overhead panel) and a LED indicating power status of the device. The bottom of the PCB features a large ground plane to ease with the noise from the many other radio heads.
I used CADSoft's EAGLE to design the schematic and the board and I will use PCB-POOL to have the boards made.
The board has a size of 4.5" x 2.45" and will fit behind most of my radio heads .... but you will see the mounting process in a later posting.
Thanks for creating this great informational resource.pcb assembly services
