PIC Prototyping Board¶

Design¶

The design was focused on producing as small a board as possible. The board had to faciliate programming and smooth operation of the microcontroller, while keeping most of the I/O pins available for use.

Even though the board is simple, routing consumed quite a bit of time. The main reason for this was that the design was restricted to a single layer.

The board uses a PIC18F4550 microcontroller. USB socket is used for power as well as programming (bootloader required). DPDT switch allows to choose the source of power - USB or external.

Here is a 3D image of the board, rendered during development.

Results¶
