[img proto1design.jpg||right]I went ahead and drew out a sketch of what I wanted to put onto the first prototype board. In this version, I will only be making 2 boards. One, which I already designed, will hold the USB port that will be extended from the Arduino for easy access and a set of 4 DIP switches. The second board will hold the PIC chip, pins for input from the receiver, and the MMC card. Originally, I was debating on whether to use the 28-pin PIC18F2620 or the 40-pin PIC18F4620, which would give me an additional 8-pin port, but upon seeing how little space I had to work with, I decided to go with the 18F2620, which is significantly smaller. At this point, I'm still making preparations for getting the first prototype up and running. At the very least, I should be able to put together a PIC board on breadboard and mount the arduino to get a pre-prototype in the next couple of days.
