0-40MHz VFO & Signal Generator Short Kit for AD9850 DDS Module (Kit)

This board will control one of the small AD9850 DDS (5 volt) modules available on eBay. It supports a 16x2 line LCD display showing the operating frequency, band and step size. The frequency can be adjusted using either a rotary encoder or two push buttons. Two additional buttons are used to select the frequency band and frequency step size.

New Version 3.10 Software now includes

Menu system allowing setting the

  • IF Frequency
  • IF Offset (VFO+IF, VFO-IF, IF-VF0)
  • Minimum Frequency & Maximum Frequency
  • Reference Oscillator Calibration and Factory Reset
  • Additional Band settings
