Description
This is a very simple and low cost circuit and comes complete with two 8 Ohm 0.25W speakers. Essentially, it is a single amplifier set up to act as a transmitter and a receiver through the use of a slide switch on the amplifier board. The slide switch may be set to speak or listen. The FK327 is an ideal class room project and the outcome is a useful device for inter-room communication or child monitoring.
