Installation Instructions
Precautions for using the module：
(1) The module is a low-power consumption module, and the power supply does not exceed 5.5 V.
(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.
(3) It is recommended to use the SMA on BNC cable to directly observe the output signal for the output signal. Poor contact or poor quality wires can cause signal attenuation or excessive noise.
(4) The supplied code is only used for supporting main control board, and does not offer a microcontroller tutorial; additional functions have to be developed by yourself.
(5) If you simply need to test the function of the module, it is recommended to use the control board from our store. Power is supplied to the DDS module first, and then the power is supplied to the control board to generate a waveform. Long press the middle button to get the function.Details Images
