Features The step frequency is adjustable from 1, 10, 100, 1000 and 10000HZ. The highest frequency of DDS signal is 65535HZ, and the lowest frequency is 1HZ. 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. Can output 1, 2, 4, 8MHZ four kinds of high-speed signals. 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 include a power supply and needs to be produced by yourself. A group of positive and negative 12V, for op amp, a group of 5V, for MCU and LCD screen.
