TTL-232R-5V-AJ USB to TTL Serial Cable

TTL-232R-5V-AJ USB to TTL Serial Cable

The TTL-232R-5V-AJ is a convenient USB-to-TTL serial converter cable designed to provide reliable communication between a computer and microcontroller-based systems. Using the proven FT232R USB UART IC, the cable converts USB data to 5V TTL level serial signals, allowing easy connection to embedded devices, development boards, and other UART-based electronics.

This version features a 3.5 mm audio jack connector, making it ideal for devices that use a serial interface via an audio-style jack. The conversion electronics are integrated within the USB connector housing, providing a compact and plug-and-play solution. Once connected, the cable appears as a virtual COM port, enabling simple communication through terminal software or programming tools.

The cable supports data transfer rates up to 3 Mbaud and is compatible with Windows, macOS, and Linux using standard FTDI drivers. With its durable construction and approximately 1.8 m cable length, it is well suited for development, debugging, and serial communication tasks in educational, hobbyist, and professional electronics projects.
