Iambic capacitive touch key circuit for Morse operation.
Warning: Last items in stock!
This is a RadioSet-GO designed capacitive touch key circuit. Two inputs with ESD suppression and two optically isolated outputs allows for iambic keying of your CW transmitter. It has high sensitivity and good RF immunity. Install it in an enclosure of your choice, add some metal contacts as keys and you will have a fun to use, solid-state key. The board comes assembled with all surface mount components and is fully tested. It accepts 12V or 3-5V input, with very low current draw (3mA on idle and 3.5mA per contact, ~10mA max, when pressed).
