Specification
The LC ICL8038 module is designed for common frequency ranges.
It is adjustable from 5 gears and generates low-distortion triangular waves, square and sine waves from 10Hz to 450KHz.
Sine wave can be used for test signals, drive signals, carrier frequency signals, etc; square wave can be used for switching signals, trigger signals, etc; triangular wave is mainly used for scanning signals.
