This USB to TTL serial converter cable adopts premium FTDI controller chip, delivering steady USB to 3.3V TTL UART signal conversion. The cable length reaches 6 feet and features a 3.5mm stereo audio jack plug, matching specification TTL-232R-3.3v-AJ for specialized serial hardware connection.
Designed with 3.3V logic voltage output, it avoids burning low-voltage microcontrollers, Bluetooth modules, WiFi units and other embedded electronic components. It supports standard UART communication protocols for data reading, firmware flashing and hardware troubleshooting.
Compatible with Windows, Linux and macOS systems. Most operating systems recognize the hardware automatically; driver installation is only required for individual old system versions. The long 6ft cord provides greater flexibility during bench testing and equipment debugging.
Perfect for electronic enthusiasts, embedded engineers, IoT project development, industrial device maintenance, router firmware updates and serial data monitoring.
Important Reminder: This cable outputs 3.3V TTL level. Do NOT directly connect to 5V circuits without level shifter to prevent component damage. Confirm pin definition of your 3.5mm jack target device before wiring to avoid short circuit.
