Introduction:
This USB to Serial UART (TTL level) adapter allows you to connect your computer through USB port and use it as a regular serial communication port. All USB protocol is handled within this adapter. There is no other device or programming required.

Product Details:
The adapter is perfect for embedded systems that require a serial connection to a computer. The board attaches directly to the USB bus via a standard type A receptacle connector. It shows up on any Windows computer as a standard serial COM port. Any applications that talk to this COM port is automatically convert to USB and back to UART to your target board.

  • USB-to-Serial TTL Adapter Cable: This 5ft cable converts a USB Type-A port into a standard UART serial COM port, making it easy to connect a PC or laptop to embedded systems, microcontrollers, and logic-level communication with 3.3V TTL serial interfaces.
  • TTL UART Interface: 6-pin header connector supports asynchronous serial data transfer with adjustable data bits, stop bits and parity for flexible communication protocols. Uses a 2.54mm (0.1 inch) pitch wire to board female connector.
  • Built-In Activity LEDs: Transmit and receive LEDs let you visually monitor data flow and power status through the translucent USB jacket.
  • Reliable Data Transfer: Supports UART communication from 300 baud up to 3 Mbaud for flexible communication protocols with microcontrollers, sensors and serial devices.
  • Wide OS Compatibility: Works across Windows 11, 10, 8, 7, Mac, and Linux systems for broad application support. Recognized as a standard COM port; no complex drivers required for basic serial communication.
