PL2303 TA Download Cable USB to TTL RS232 Module USB to Serial

This is PL2303 TA Download Cable USB to TTL RS232 Module USB to Serial.

The cable is the easiest way ever to connect to your microcontroller/Raspberry Pi/Wi-Fi router serial console port. Inside the big USB plug is a USB to Serial conversion chip and at the end of the 1M cable are four wire red power, black ground, white RX into the USB port, and green TX out of the USB port.

The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V levels for interfacing with the most common 3.3V logic level chipsets.

Also handy for hacking Wi-Fi routers to install alternate OSs, or nearly any other 3.3V logic serial port. This is easier to use than an FTDI cable in many cases because the wires are separated.

Pin Connection : 

• Red: +5 V
• Black: GND
• White: RXD
• Green: TXD
