All connectors, switches, the speed pot, and components are board mounted, making the keyer completely self contained on the board. No external parts or wires are required (excepting battery leads).

It has many of the features of a high end keyer while remaining very user friendly. The EZKeyer III been designed and programmed by Craig Johnson, AAØZZ, of PIC-EL fame, and the commands are entered directly with the paddles rather than scrolling through menus.

Room is reserved in the enclosure for a 3 AA battery pack, they should last a loong time, approx. a year.

This kit is an easy kit to build, only taking about an hour to complete. All parts are through hole parts making for an easy build. All connectors and switches are board mounted which eliminates point to point wiring, and after all the parts are installed it's ready to try out. The kit includes Everything required to build the keyer - switches, speed pot, connectors, speaker, programmed PIC, components, AND a nifty enclosure - everything except the batteries and solder.
