The Iambic Keyer Shield for Arduino contains a DAC, OpAmp, and speaker to produce shaped sine waves without clicks or harmonics that's loud enough to hear across the room. The LCD will decode as you send giving you excellent feedback on your letter and word spacing. A menu-driven user interface makes it easy to configure.
This is an unassembled kit that contains all thru-hole components. Arduino not included.
Note: LCD color may vary.
