LORDWORLD Serial Bus Servo Driver Board ESP32-WROOM-32 253 servos

SKU CH-Q4SP-GGJ7P

Controls up to 253 serial bus servos via ESP32-WROOM-32 with USB Type-C and Raspberry Pi power integration

  • Control up to 253 ST / RSBL serial bus servos simultaneously
  • ESP32-WROOM-32 module enables wired and wireless communication
  • Onboard USB Type-C port allows direct servo control
  • Integrated 5V buck regulator powers Raspberry Pi via GPIO UART
  • 9–25V wide voltage input matches servo supply requirements

Serial bus servo controller for up to 253 units

This board drives up to 253 ST or RSBL series serial bus servos simultaneously using the ESP32-WROOM-32 module. It accepts a 9 to 25 V supply that must match the servo voltage. The board provides wired and wireless communication options and includes multiple control demos for various host controllers.

Capacity scales to 253 servos

Comfortable headroom exists for large robotic arrays up to the 253 servo limit. The 9 to 25 V range covers common battery packs and bench supplies but the input must match the servo voltage exactly. Systems needing more than 253 servos or a different voltage domain cannot use this board.

Integrates with Raspberry Pi and USB hosts

An onboard USB Type-C port allows direct servo control from a PC. A GPIO UART link connects to Raspberry Pi 4B or 5 while the integrated 5 V buck regulator powers the Pi for tidy cable management. Builds without a Pi or USB host must rely on the ESP32 wireless link alone.

Questions about this item

Will this driver board let my Raspberry Pi 4B power and command 253 serial bus servos through the GPIO UART?

The board includes a 5 V buck regulator that powers the Pi and communicates via GPIO UART, so the Pi can send commands to all 253 servos without extra wiring.

How can I verify the ESP32-WROOM-32 module is communicating with the servos after I connect the USB Type-C port?

Plug the USB Type-C into a PC, open a serial terminal at the demo baud rate, send a ping command and watch each servo return its ID and position data.

Does the package include the ST or RSBL series servos and the 9–25 V power supply, or must I buy them separately?

Only the driver board is supplied; the 253 servos and a matching 9–25 V power source must be purchased separately.
