DTECH USB to TTL Adapter 3.3V 4 Pin UART Debug Cable Prolific Chip LED Indicators PL2303 IC Serial Converter Output 3.3 Volt for Windows 11 10 8 7 XP MAC Linux Easy Debugging Programming (1.8M)

The 6ft USB to TTL serial adapter is designed for USB to TTL electronic projects (with 4 pin 0.1inch pitch female header) to connect devices with 3.3V logic level UART signal interface to laptop computers via USB port USB to TTL serial cable 3V3 (4-way output flying lead) provides access to UART (transmit) Tx, (receive) Rx, VCC (5V) and GND. Four different colors represent different wiring functions: white represents TXD transmit data, green represents RXD receive data, red represents VCC circuit power supply voltage (5V), and black represents GND ground The integrated circuit board of the USB to TTL serial cable is encapsulated in a transparent plastic shell, which protects the components while allowing a clear view of the internal components. Different colored indicator lights (blue and green) are used to send and receive data, TX (blue), RX (green). Contains TX, RX and GND pins for easy connection to your serial device This USB to TTL serial cable uses the original PL2303 chip module encapsulated in a USB 2.0 Type A male connector, which has wider compatibility and more reliable data transfer rates 4-pin 3.3V USB to TTL conversion cable, compatible with Windows 11,10, 8, 8.1, 7 (32-bit and 64-bit), XP/Vista, stable and secure, it is an ideal USB 2.0 debug cable for vendor ID rewriting, routers, GPS, set-top boxes, transmitters, flash firmware on hard drives, etc
