K40 Features
The K40 is a small low power PIC based CW keyboard that is packed with features and is inexpensive. The single board has a PS/2 style keyboard connector, on board piezo speaker, circuitry to drive an off board speaker, low level audio output, an iambic keyer interface, and open collector PTT and Key outputs. The design uses two 14 pin PIC processors, requires no crystals, and has an on board 5 volt regulator that powers both the K40 PC board and the attached PC keyboard.
