CPLD Breakout Board in DIL Format
For programmable logic projects
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.
Materials
Gerber file
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
