LORDWORLD ESP32 Servo Driver Expansion Board 253 Servos

SKU CH-247D-KETQC

Controls up to 253 serial bus servos via ESP32 with Wi-Fi, Bluetooth and ESP-NOW for remote robot projects

  • Controls up to 253 serial bus servos simultaneously
  • Wide 6-12V input range matches servo voltage needs
  • Built-in WiFi, Bluetooth and ESP-NOW enable wireless control
  • Automatic download circuit simplifies program uploading
  • Compact design fits space-constrained robotics projects

ESP32 Servo Driver for 253 Serial Bus Servos

This LORDWORLD expansion board is an ESP32-based IoT edge device built to drive SC and ST series serial bus servos. It suits makers and robotics developers who need to coordinate large numbers of servos from a single compact controller. Built-in WiFi, Bluetooth and ESP-NOW enable wireless operation and remote debugging.

Simple Upload Circuit

An automatic download circuit streamlines firmware uploads so code can be pushed without manual boot toggles. The board accepts a wide 6-12V input range, but the supply voltage must match the servo voltage to avoid damage. Adequate current capacity is essential when driving all 253 channels simultaneously.

For Large-Scale Servo Projects in Tight Spaces

The compact footprint fits space-constrained robots, hexapods and animatronics where dozens of servos must share one controller. Open-source web tools and example structures accelerate development. Builders needing only a few servos or a different bus protocol should consider simpler driver boards.

Questions about this item

How can I verify the board is communicating with all 253 SC or ST servos after wiring?

Power the board with 6-12 V matching the servo voltage, open the open-source web app via Wi-Fi or Bluetooth, and confirm each servo ID responds to test commands.

What ships with the expansion board and what must I source separately?

The board itself is supplied; you must provide a 6-12 V power supply, the SC or ST serial bus servos, and any mounting hardware.

Which servo series should I select to work with this driver?

Choose SC or ST series serial bus servos, as the board is designed specifically for those protocols and supports up to 253 units.
