If you are tired of connecting the same I/O devices every time you prototype a new project then this board could save you a lot of time. All the necessary pins of the devices on the board are accessible through headers that allows easy connection of the board to a breadboard circuit or other development boards (Arduino, etc) using jumper wires.

I previously showed you my PIC32 proto board I made on verroboard (http://www.blogspot.com/2016/02/pic32-development-proto-board-on.html). To make the proto board “more of a product” and easy to reproduce, I was working to make the proto board on a PCB. I used ExpressSCH to draw the schematic, and used ExpressPCB to design the PCB. Once designed, Professor Bruce Land got the PCB made from ExpressPCB themselves. The PCB is just to be a basic board with the PIC32MX250F128B placed on it. The power supply connections are provided as are external oscillator connections (if needed). Additionally, there is a nice convenient power supply input connector (standard 2.5mm jack/plug). All the IO pins along with power (Vin and +3.3V) and ground are placed on a SIL connector at the edge of the board so that the board can be conveniently placed on a breadboard for experimenting and prototyping (see pictures below). It's a nice little 2-layer PCB measuring only 3.1 inches by 1.8 inches. I chose t...
