The LX16A-Bus library is an open-source control library for certain popular models of serial bus servos such as LX-16A or LX-224. Works for other boards with Arduino core, e.g. ESP32 or STM32. Uses hardware serial for communication: standard RX and TX pins.
This library supports the Bus Linker. It does not need any other microchips or breadboards. Can control servos directly without the Bus Linker, but in that case it is write-only: sends commands and does not read; for many applications it could be enough.

The library has the following features:

  • Compatible with 3-pin serial bus servos like LX-16A and LX-16A
  • Uses TX and RX pins
  • Generally, needs the Bus Linker; but can also send commands without it
  • Contains examples of programmatic acceleration and deceleration
  • Object-oriented code
