BLOCK DIAGRAM & BOARD LAYOUT The diagram shown below illustrates the component layout for the Digital QRP Breadboard. The board size is 6”x9” and contains most of the components needed for the various projects planned in the coming issues. Because of uC I/O port limitations, not all capabilities can simultaneously be available, but you’ll be able to set jumpers to allow various combinations (e.g., LCD or 7-seg displays, keypad or keyboard, etc.) A prototyping area is available to allow addition of your own components for that “special” application you have in mind. Further, a unique feature is the daughter board area to the left of the keypad. We’ll use this “plug-in” board in future columns to add some specialized functionality – e.g., a DSP pre-processor to beef up signal processing capabilities, a PLL to serve as the basis for a stable VFO, etc.
