DDS Function Signal Generator Module Sine Square Triangle Sawtooth Wave Low Frequency LCD Display Digital DIY Module

Features:
Compact Size --- Small size, powered by DC 7V-9V, easy and portable for use.
DDS frequency range --- 1Hz-65534Hz, high-speed frequency (HS) output up to 8MHz.
Flexible Operation --- DDS signal amplitude of the offset amount can be adjusted separately by two potentiometers.
DDS signals --- sine wave, square wave, sawtooth, reverse sawtooth, triangle wave, the ECG wave and noise wave.
Easy Use --- LCD display for clear reading, intuitive 5 buttons for convenient operation. The power automatically restore the last used configuration.
Key Functions:
The UP output waveform select
The DOWN output waveform select
LEFT output frequency -
RIGHT output frequency +
STOP / RUN the output stop / start
UP key waveforms order:
ECG = electrocardiogram wave (in the OFF state, the left and right keys to set the output frequency. Middle button start, all of the following waveform set)
Rev Sawtooth = reverse sawtooth
SawTooth = sawtooth
Triangle = triangle wave
Square = square wave
