Features 1、The stepped frequencies are 1, 10, 100, 1000 and 10000HZ adjustable. 2、The highest frequency of DDS signal is 65535HZ and the lowest frequency is 1HZ. 3、Four kinds of high-speed signals, 1, 2, 4 and 8MHZ, can be output. This signal can be used to unlock the single chip computer (as an active signal), and the signal amplitude and offset can be adjusted. 4、The main board kit of DDS signal generator can output DDS signals such as pulse wave, positive and negative sawtooth wave, triangular wave, squarewave, sinusoidal wave and noise wave. 5、The kit does not contain power supply and needs to be manufactured by ourselves. One set of positive and negative 12V is for op amp and one set of 5V is for MCU and LCD screen. 6、All of them adopt direct insertion components, which are easy to install and suitable for DIY tools.
