Fun and useful for the price but a lot of noise.

Received on time well packed.When implemented into signal generator found that generator has some interruption for some frequencies.I ordered another one from AliExpres and it works perfect.Signal generator from Amazon is in the trash.

The unit (HC-SR08 DDS_AD9850) may not start every time it is powered on, or it may take some time to finally start outputting a signal. The code controlling it is not the issue (proper reset sequence has been implemented), and the same code works flawlessly with another unit (same board layout, from another distributor). The most noticeable difference is that C8 (10uF capacitor, power supply decoupling) is of a different type, seems to be a polarized version in the defective board, and the solder looks "cold" in both ends. I wish I had the option to contact the seller before posting this review, but at this point this unit is not usable for me.UPDATE: HiLetgo Customer Service replied quickly and provided a resolution; for this reason I changed my original rating from 1 to 3 stars.

Many of these modules available on the Internet are duds but this one was perfect. It works within specifications and the quality was just fine.

This is a nice part to make a signal generator. Mine works great and is handy very often.

This review is for AD9850 Signal Generator Module board. This board uses AD9850 and it is capable to produce 0-40Mz Sine and Square wave. In order to program the output frequency, one of the ways is to use Arduino. Since this board can handle both 5v and 3.3v, it can work with either UNO/NANO, due or other Arduino boards. The Arduino library can also be found online easily. For me I end up using an Arduino UNO with a prototype shield as this module is breadboard friendly. One friendly reminder of this board, it can generate square wave with 5v amplitude. For sine wave, it can only generate around 1v peak to peak voltage. Also make sure you adjust the POT for the duty cycle for the square wave. I made a mistake initially and I didn't get any square wave output due to my pot was set to 0% duty cycle. Note that the POT has no effect on the sine wave output.Since I have no problem program the frequency as the board claims, I would recommend this board.
