Features
1. Allows controlling up to 253 ST / RSBL series serial bus servos at the same time
2. 9~25V wide voltage input (the input voltage and the servo voltage must be matched)
3. Based on the ESP32-WROOM-32 module, supports wired and wireless communication
4. Wired Control Mode---Supports sending JSON commands to ESP32 for controlling the serial bus servos, or directly sending control commands to the servos via USB Type-C port. Comes with Python demo
5. Wireless Control Mode---The Bus Servo Driver HAT (A) Will Automatically Establish A Hotspot after Powering on, Allows Users To Connect And Control The Driver board Via Mobile Phones, Tablets And PCs with the Cross-Platform Web Application we provided
6. Provides multiple control demos for different host controllers
7. Supports controlling the serial bus servos directly via onboard USB Type-C port
8. Suitable for Raspberry P 5 / 4B, powering the Pi via integrated 5V buck regulator circuit and communicating through GPIO UART interface, neat cable management
9. ESP32 Controller, Extensive Resources, Easy Secondary Development---Built-In WiFi And Bluetooth, As Well As ESP-NOW Support, For Remote Control And Servo Debugging
11. Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos

Comes with Online Tutorial and Online Development Resource, Please check: n9.cl/rtgv2
