The DFRobot Maker Community is in place to help users with DFRobot product issues, help with project implementation and general engineering-related queries. It is also a place where you can showcase your work and share ideas with other makers.

  • This is a friendly forum - rude or offensive posts will not be tolerated.
    This is a community for makers and not an advertising space - links to commercial concerns will be considered spam and deleted. Repeat offenders will be banned.
In order to help each other as quickly and efficiently as possible, we suggest following these guidelines:


First, if you haven’t already, check the product wiki for information:
You can search for the product you are having problems with by entering the SKU in the search bar (e.g. ROBxxxx, KITxxxx, SENxxxx, etc.) You can also use the product name to search.

If you have checked the product wiki and haven’t found what you need, please do post questions on our forum!

In your post please include the following information if you can:

• The SKU of the product you are having issues with (e.g. ROBxxxx, KITxxxx, SENxxxx, etc.)
• What is the intended function of your project?
• Are you using any libraries? Links to the source are helpful!
• Provide a sample of the code you are using between code tags so we can easily check it for any errors, e.g.:
Code: Select all

void setup() {
  // put your setup code here, to run once:
void loop() {
  // put your main code here, to run repeatedly:
Feel free to provide any other details that you think might help - the more detail, the better.
When you have posted, one of our moderators will get back to you as soon as we can!

(Of course, you don't have to follow these guidelines, but it might take us longer to help you if we don't have enough information!)

Do you see any mistakes on our wiki? Spelling, grammar, technical errors? Please do let us know on the forum so we can make it better.

I've purchased quite a few of your DSS-M15S servos and other DRFROBOT products before for use in RC based Robotics applications at our Mind Labs STEM education center and we have previously been quite satisfied. Just received two newly purchased DSS-M15S Servos (this time sold by Amazon Prime) that seem to be very defectively manufactured. Both servos exhibited exactly the same defects. They both were grossly non-linear and very jerky in exactly the same way when sweeping them with a smoothly and relatively slowly increasing and decreasing PWM servo test signal. These servos would never have passed any sort of useful final test so my guess is that none was performed. Certainly such defectively manufactured servos should never have been shipped to a customer. If you are unaware of this problem I believe you should recall these defective servos immediately before they significantly negatively impact customer perception of DFROBOT's products.
