This is the same printed circuit board that comes with the complete computer kit. If you have many of the components in the complete kit, you can save some money by buying this bare board. The computer kit instructions has a complete parts list for the computer kit on page 65 that you can refer to. I buy the parts from Jameco Electronics, and you can buy any parts you might be missing from them. If you have any questions about the exact parts you need, contact me and I will help you pick the correct parts.
