AD9850 DDS Signal Generator Module 0-55MHz with LCD Display

Adjustable Frequency Output from 0 to 55MHz This DDS signal generator module delivers a continuous frequency range from 0 to 55MHz, adjustable in precise 1Hz increments. The built-in LCD display provides clear readouts, making it straightforward to set and monitor your chosen frequency during testing and development work. The module supports six frequency bands, giving you flexibility across a wide spectrum of applications. Power Supply Requirements For reliable operation, an input voltage between 8V and 9V with a current of around 200mA is recommended. The onboard 78L05 voltage regulator helps maintain stable performance within this range. Please note that a 12V input should only be used for short-term testing, as prolonged use at this voltage will cause the board to heat up. Connection and Setup The module uses a 14-pin interface, with pin 8V GND serving as the 8V power supply connection from the motherboard. The encoder connects via a 7-pin interface positioned in the middle, linking to the digital matrix input. For the signal output, connect the 5p and 6p pins as shown in the accompanying diagram. This straightforward layout allows for quick integration into your existing test bench or project setup.
