Review: Great serial servo driver - Works pretty much as stated. The jumper move around can be a pain and might leave you scratching your head on what is going on. The waveshare library also has the wrong pins stated for the esp
Review: Worked exactly as I expected - I am using it on my SO-ARM101 robot arm and have had zero issues. Very small which is great and mounts on SO-ARM101 are made for this board.

## Features

- Compatible Servos--- Supports ST/SC series bus servos, and can directly power the servos via DC power jack, supports selecting power supply input according to the servo used
- UART serial bus control--- Allows controlling up to 253 SC/ST series serial bus servos at the same time, supports receiving the operating status and various information feedback of each servo
- Two Power supply methods--- Onboard DC5521 power jack and screw terminal for easy integration into existing projects. Supports UART and USB control--- Switching the control mode by selecting A or B via the jumper
- Suitable for more Applications via UART--- Supports directly controlling the serial bus servo via UART communication, and provides SDK which is compatible with various hardware platforms, please refer to the product's Online Wiki for more details
- Easy to use with USB control----Connect the driver board to the host via a USB cable to easily control the serial bus servo and receive data feedback, speeding up the project prototyping process
- Comes with Online Tutorial and Development Resource, Please check: n9.cl/rs537

### ⭐⭐⭐⭐⭐ Worked exactly as I expected

### ⭐⭐⭐⭐⭐ Plug-and-play... Works great with an ESP32 w/ UART control!
*by J***T on September 7, 2024*

I've been dabbling in hobby robotics for a few months, but have previously been limited to standard RC servos. I needed more control for an animatronic project idea, and had the chance to try out an SC15 servo, but it needed a controller. This board was that controller. In all honesty, there's little to write about, because it just works - I set the jumpers to UART mode, plugged the pins into my ESP32's serial pins, connected 5.5V to the power posts, loaded up the Waveshare examples, and... voila! I had programmable servo control, and I was able to exercise both the control and feedback functions. The only thing that concerned me a little is that the sockets leading to the servo are a little tight, and the plastic shell started to work loose from the pins when I tried to remove the cable. However, I worked around that by loosening the cable slightly using a flathead screwdriver, before pulling it free. These are compact and effective boards at a great price - highly recommended!
