Hello, Thanks for the reply, can I use TTL-RS485 module to send and retrieve data through UART connection with a microcontroller i.e. (Arduino or Esp-32 )
Hi there, pls refer this link for its control method: https://drive.google.com/drive/folders/1kPvTBzUBKv7auwGpHf5mYt7avwqtHKNg?usp=sharing

Hello, so if i want to create a robot with 18 servos, how could i connect them to arduino and take feedback signals from all of them, I am aware that it is done through serial communication but do i need a converter chip in between, and would it be able to send signals to all servos and take feedback from them back to the arduino?
Hello,
An Arduino alone cannot retrieve information from the servo through direct connections. If you wants to send signals to the servo and receive feedback, it is recommended to purchase a bus servo controller, which primarily utilizes the 74HC126 chip for this functionality.
-
What is the specific connector type is used on the sides of the servo? I have purchased it but I would like to use the locking connector rather than dupont connectors.
Hi there, the connector is PH2.0-3P
-
Are there drawings of the main servo horn available? Also, what are the screw sizes? Thank you.
Hi there, please contact our email with your order number for servo horn: support@hiwonder.com They are M2 self-tapping screws.
-
Hi, Can I use this as a regular servo? use it with pwm control?
It is controlled by UART serial command
-
Why doesn't it work with "Serial Bus Servo Controller" ? The run button does nothing when pressed. My Windows is 11 . It does not recognize it as a com port
Please send us video about the operation to support@hiwonder.com
-
what is the gear ratio on the Hiwonder HTD-45H?
Servo ratation speed: 0.18 sec/60u00b0 11.1V
-
Hi, Can I use this as a regular DC motor ? If yes, what is the RPM ? Thanks,
Yes, you can. The RPM is 0.18sec/60° 11.1V
