Mini DDS Signal Generator Dual Channel Output Pulse Generator 1KHz-68MHz Module

Mini DDS Signal Generator Dual Channel Output Pulse Generator 1KHz-68MHz Module

Description:
HM345 is a small signal generator which has two output, one can be 10KHz frequency, variable duty cycle pulse signal; the other way can be 1KHz to 68MHz pulse signal. The module is easy to use, input frequency data can be in by keys, the output frequency is updates immediately then.
