FE-URT-2 Universal USB Programmer With TTL, RS485 And UART Interfaces For FEETECH Smart Serial-Bus Servos
The FE-URT-2 is a universal USB-to-serial-bus programmer and debugging adapter designed for configuring, testing, and controlling compatible FEETECH smart servos. It converts USB communication from a PC into half-duplex TTL or RS485 serial-bus signals, allowing developers to connect SCS, STS, and SMS servo families for parameter configuration, motion testing, status monitoring, and multi-servo development. The updated board uses a USB Type-C connection and CH343P USB-serial controller for convenient connection to modern computers.
In addition to PC-based debugging, the FE-URT-2 provides a 2.54 mm UART header for integration with microcontrollers such as Arduino, ESP32, and STM32. A serial-signal level selection switch allows the board to work with TTL and RS485 servo systems, while dedicated servo and external-power connectors simplify bench testing. With FEETECH software and protocol support, users can configure servo IDs, baud rates, position parameters, speed, angle limits, and other supported smart-servo settings.
