CPLD Breakout Board in DIL Format

For programmable logic projects

CPLD Breakout Board in DIL Format
CPLD Breakout Board in DIL Format
CPLDs tend to have a large number of pins practically inaccessible to the soldering iron and so do not lend themselves readily to use in homelab and experimental projects. The BoB described here brings out the connections to header sockets, allowing you to use the CPLD as easily as a DIL IC on prototyping boards or straight in prototypes.
