With ICL8038 and high-speed operational amplifier, the precision is higher.
It can output sine/triangle/square wave/forward and reverse sawtooth waveform.
Frequency range: 5Hz~400kHz; Duty cycle range: 2~95% (adjustable)
Dual power amplifiers are supported, which will not block the capacitance and ensure the distortion of high and low frequency signals.
Adjustable frequency and amplitude.
The frequency adjustment has the function of coarse adjustment and fine adjustment.
All are through-hole components, easy to install.

Attentions
1. All products (except those specially marked) are loose parts, and the buyers need to solder, assemble and debug by themselves. If you need finished products, you can contact customer service to buy them.
2. If there is a problem with the product you received, or there is a problem during the soldering and assembly process, please contact us as soon as possible.
3. Do not including battery
