AJMRTC PL2303TA USB to TTL RS232 Serial Download Cable, 3 Pack, USB to UART COM Adapter, Supports Vista, Windows 8, Windows 10

AJMRTC PL2303TA USB to TTL serial cable is a widely used debugging and programming tool for embedded engineers and electronics hobbyists. It converts USB signal into standard TTL UART serial signal, which lets your PC communicate with microcontrollers, development boards, GPS modules and other serial devices.

After driver installation, the system recognizes it as a standard COM port. It supports adjustable baud rates for different serial device requirements. It outputs 3.3V logic level, which avoids burning low-voltage MCU chips that cannot tolerate 5V RS232 voltage. The cable is pre-terminated, so you only need to connect TX, RX and GND pins to your target hardware for log reading or firmware flashing.

It is frequently used for IoT module debugging, router firmware flashing, sensor data logging and student electronic experiment projects. Note: You need to install the matching PL2303TA driver before use. This cable is TTL level, not standard RS232 ±12V level.
