LORDWORLD Serial Bus Servo Driver Board for Raspberry Pi Jetson Nano 253 Servos 12.6V

SKU CH-J0XH-BN2K1

UART serial bus driver board controls up to 253 ST/SC servos simultaneously with 9 to 12.6 V input for Raspberry Pi and Jetson Nano projects

  • Controls up to 253 servos simultaneously with sufficient power
  • Wide 9–12.6 V input range matches servo voltage needs
  • Integrates control circuit for stable serial bus operation
  • Compact design fits space-constrained Raspberry Pi projects
  • Connects to host or MCU for flexible servo control

253-Servo UART Driver Board

This LORDWORLD board connects a host computer or microcontroller to ST and SC series serial bus servos. It is designed for Raspberry Pi and Jetson Nano platforms and integrates the power supply and control circuitry onto a compact PCB. The board suits robotics and automation projects that need many servos driven from a single UART link.

Sustained Multi-Servo Operation

The board can address up to 253 servos simultaneously when a sufficient external power source is provided. Stable operation depends on matching the 9 to 12.6 V input voltage to the servo specifications. The integrated control circuit maintains signal integrity during continuous multi-axis movement.

UART Bus Voltage Constraint

Communication runs over a single UART serial bus, so bandwidth is shared across all connected servos. The 12.6 V maximum input sets a hard ceiling on servo voltage compatibility. Builders who need more servos than the address space allows or a different voltage range must choose another control method.

Questions about this item

How much heat or noise does the board generate when driving 253 servos continuously?

The board integrates the control circuit for stable operation, but heat and noise levels depend on the total servo load and the cooling in your enclosure.

Which host board and power supply do I need before this driver will work?

You need a Raspberry Pi or Jetson Nano as the host and a 9–12.6 V supply that matches the voltage rating of your ST/SC series servos.

Can I keep using my existing ST/SC serial bus servos with this driver?

Yes, the board is designed for ST/SC series serial bus servos and can address up to 253 of them on the same UART bus.
