🔍 Explore every detail

FE-URT-1 is carefully designed to facilitate the work with complex robotic systems. With the integrated USB serial port chip and linear low-voltage differential voltage regulator circuit, it can easily convert USB signal to 5V or 3.3V serial signals. On the converter board, the signals are divided into two levels: one for the asynchronous half-duplex RS485 port, ideal for SMS servos, and the other for the asynchronous half-duplex TTL bus port, designed for SCS servos.

The innovative use of hardware time multiplexing for input and output signals eliminates the need for additional IO pins for control, greatly simplifying the code and reducing the burden on the microcontroller. With a MINI USB interface for connection to a computer and standard 2.54mm pins for UART, along with specific 5264-4AW connectors for SMS and 5264-3AW for SCS servos, the URT-1 ensures a safe and reliable connection. Although the URT-1 provides 5V power from USB with overload protection, for a larger number of servos, it is recommended to use an external power supply to ensure optimal operation.
