Waveshare Serial Bus Servo Driver Board, Integrates Servo Power Supply and Control Circuit, Applicable for ST/SC Series Serial Bus Servos, Small in Size, Easy to Integrate

Works great with every PC and python software I've used to program and control Feetech STS3215 servos. Would definitely buy again. Completely compatible with Feetech branded bus control board.

As I step up my hobby robotics work, simple RC servos just don't make the cut for some use cases. I found the Waveshare SC and ST series servos to be a full-featured and very capable next step. This driver board is capable of controlling multiple SC/ST servos on a single bus, either via serial or usb. The serial option integrated well into my Esp32 projects, and the board handles the power distribution to the servos. I will caution that the servo cable connector is pretty tight - it's very secure once attached, and deserves some finesse when unplugging it - mine had a tendency for the plastic housing to slide up the pins, though the pins themselves stayed firmly soldered. All told, this is a very affordable option for gaining the ability to use the Waveshare servos. Plenty of docs available through the waveshare wiki.

Disclosure I haven't had time to hook it up and run it through some tests. I will say it seems pretty well built. The soldering is all really good and the components all seem pretty good quality. It isn't as cheap as some others I've had. I'll have to update once I've had a chance to run it through some tests.

HORRIBLE TECH SUPPORT,ALMOST AS BAD AS HIWONDER !!! wareshare responds but apparently their tech support knows nothing, as they always refur your questions to the engineer, who if they respond at all its with a stupid reply and just running you around in circles and you get NOWHERE ! they dispite their claim do not care !!
