## Summary description

DELOCK 63989 USB cable sold as a single unit. A general-purpose USB connection cable designed for linking compatible devices such as peripherals, chargers and data ports. Packaged quantity is 1 piece. Suitable for replacing or adding a standard USB lead where a dedicated cable is required.

## Long description

DELOCK 63989 — single pack, standard connection cable is a USB 2.0 Type-A to UART TTL converter that provides a 3.3 V logic-level serial interface for connecting embedded devices to a PC via USB. The adapter exposes a 6-pin header with TX, RX, CTS and RTS signals and includes a 3.3 V output to power target boards or modules. It is intended for serial communication tasks such as firmware programming, debugging and data exchange with microcontrollers, routers and other TTL-level devices.
Advantages
The DELOCK 63989 converter supports USB 2.0 connectivity and delivers a stable 3.3 V logic interface, reducing the need for additional level-shifting components. Its compact 6-pin header integrates hardware flow control lines (CTS, RTS) alongside TX and RX, enabling reliable serial transfers and supporting devices that require RTS/CTS handshaking. The included 3.3 V power output simplifies powering small target circuits during development and testing.
Suitable for
 Firmware programming and bootloader access on microcontrollers
 Serial console access to routers, switches and embedded Linux devices
 Debugging and logging of serial data from sensors and modules
 Development and prototyping of IoT and embedded systems requiring 3.3 V UART
Key specifications
 Interface: USB 2.0 Type-A to UART TTL
 Logic voltage: 3.3 V
 Header: 6-pin with TX, RX, CTS, RTS and 3.3 V output
 Signals: asynchronous serial TX/RX with hardware flow control lines
 Power output: 3.3 V supply for target devices
 Application: serial communication, programming and debugging
How to use
Connect the converter to a host PC using a USB 2.0 Type-A port. Wire the TX and RX pins to the corresponding RX and TX pins on the target device, and connect CTS/RTS if hardware flow control is required. If the target requires power from the converter, connect its power rail to the 3.3 V output while observing the converter's current limitations. Install any necessary USB serial drivers on the host system so the device is recognized as a virtual COM port, then open a terminal or programming tool configured for the target baud rate and serial settings.
Usage recommendations
Verify the target device operates at 3.3 V logic before connection to avoid damage. Use a common ground between the converter and the target. Secure wiring to prevent accidental shorts during firmware updates or solderless testing. Consult the operating system's driver documentation for correct virtual COM port setup and recommended baud rates.
