This board is designed for the development of small custom circuits that can be used with the FLEX Full and FLEX Light Microchip dsPIC development systems. The board makes several common pinholes available for connecting electronic components.

The patterns marked "piggybacking" in the image to the right are pins which come from the piggybacked FLEX board. Each pin on the piggybacking rows is part of the connection to the host FLEX board.

The remaining board surface is divided into the most common pinhole patterns:

1. Standard 2.54 mm pattern
2. Standard 2.54 mm pattern with alternate phases (useful for RJ45 and RS232 connectors, etc.)
3. Standard 1.27 mm pattern (useful for connecting typical SMD components)
4. Standard 5.08 mm pattern (useful, e.g., for clamps)
