The ICL8038 is a precision oscillation integrated circuit with multiple waveform outputs. The frequency and duty cycle of the output waveform can also be controlled by current or resistance. Because the chip has a frequency-modulated signal input, it can be used to frequency-modulate low-frequency signals.
Produced with a low frequency drift when the temperature changes, the maximum does not exceed 50ppm / ℃; With sine wave, triangle wave, square wave and other function signal output; Sine wave output with less than 1% distortion; The triangular wave output has a high linearity of 0.1%; Wide variation of work cycle, adjustable from 2% to 98%; Easy to use, requiring only minimal external conditions.
This module is designed for the common frequency range. It can be adjusted in 5 gears and can generate low-distortion sine wave, triangle wave, square wave and other pulse signals from 10Hz to 450KHz.
Sine waves can be used for test signals, drive signals, carrier frequency signals, etc. Square wave can be used to switch signals, trigger signals, etc. The triangular wave is mainly used for scanning signals.

This seems like it would do what I need it to do, except the capacitor at C10 literally blew in less than a minute. I replaced it with a 500uf capacitor which seems to be working, but the potentiometers on the board are poorly explained and difficult to adjust. Anyone know of better made version of this module?

I have quite a few signal generators including a fully developed 8038 function generator so I know how to set these up and what they should do. I was hoping to use this in a portable signal generator but this NOYITO ICL8038 Signal Generator Module was defective out of the box. I checked the 8038 IC and it clearly showed it was defective.

It does work with the included software, but sometimes have to replug few times in a different order (power, USB) to get recognized. Once it is working, it is stable, but software is horrible.

I may have voided the warranty by fixing the problem... I suspect C10 is 0.1uF with how fast the output dies at lower frequencies.. I stacked on a 10uF and now there is much more amplitude that the amplitude pot actually works now.

I bought this to generate a 250Hz sine wave. The waveforms in all three modes - sine, square, sawtooth - look good on a scope. It's easy to set up and adjust. I would give it five stars easily, except that it arrived without any instructions at all and I had to e-mail the seller to get them. The instructions are perfectly understandable, but could use a rewrite by a native English speaker.
