Features The highest frequency of DDS signal is 65535HZ, and the lowest frequency is 1HZ. The step frequency is adjustable from 1, 10, 100, 1000 and 10000HZ. The DDS signal generator mainboard kit can output DDS signals such as pulse wave, positive and negative sawtooth wave, triangle wave, square wave, sine wave and noise wave. It can output four high-speed signals of 1, 2, 4, and 8MHZ. This signal can be used to unlock the microcontroller (as an active signal), and the signal amplitude and offset can be adjusted. The kit does not contain a power supply and needs to be produced by yourself. One set of positive and negative 12V is used for op amps, and one set of 5V is used for MCU and LCD screen.
