The USB to Dynamixel R is an USB to RS485 level serial UART converter PCB incorporating FT232RQ USB to serial UART interface IC device which handles all the USB signalling and protocols

The PCB provides a fast, simple way to connect devices with a RS485 interface to USB.

Each unit contains a small internal electronic circuit board, using the FT232R, a USB type-A connector and a MOLEX 4 pin connector to interface with the Dynamixel bus. The integrated electronics also include an RS485 transceiver plus Tx and Rx LEDs which give a visual indication of UART traffic. The PCB is USB powered and USB 2.0 full speed compatible. Each PCB supports a data transfer rate up to 3 Mbaud

This adapter requires USB drivers, available free from, which are used to make the FT232R on the PCB appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT232R on the PCB through a DLL

Each unit is wrapped with a transparent heat shrink tube to protect the electronics although still allowing you to have feedback from the Tx and Rx LEDs.
