Bill of Materials (BOM)
This is the complete BOM (Bill of Materials) for the Turnkey MorseKOB Interface. It includes the quantity of each item required to build 1 unit — no yield factor is added to the part quantity. Pricing for each line item from Mouser and McMaster-Carr is current as of 10/26/14 has been provided for reference. Digi-Key and other sources may be used and it's possible that you could find better prices on small quantities from numerous suppliers. However, be aware that some suppliers have minimum orders and each will charge shipping.
The interface can be built using perfboard or any other prototyping method if PCBs are not available. It is, however, much easier to use a PCB.
