USB To TTL PL2303 Description:

USB To TTL PL2303 PL-2303HX is a low cost and high performance USB-to-Serial Bridge Controller. The PL-2303HX provides a convenient solution for connecting an RS-232 like full duplex asynchronous serial device to any Universal Serial Bus (USB) capable host,

Flexible signal level requirement on the RS-232 like serial port side also allows the PL-2303HX to connect directly to 5V, 3.3V, or 2.5V devices, Works well with Linux and Mac. Does not work so well with Windows. If you are running Windows then buy a FTDI FT232RL board instead.

  • It is also use in cellphones, XBOX360, GPS serial communication, vehicle inspection, and test DVD flash, and so on.

USB To TTL PL2303 Features

Currently, USB to TTL-level UART converters are use extensively by students and hobbyist as they can be directly interface to microcontrollers.

  • Its color is Blue.
  • Its package weight is 15g.
  • Its net weight is 5g.
  • Its size is 50 x 15 x 7 mm.
  • It contains 500mA self-recovery fuse for protection.
  • It has two data transmission indicator. And these indicators can monitor data transfer status in real-time.
  • The board of USB to TTL converter is coat by the high quality transparent heat-shrinkable sleeve.en.wikipedia.org
  • This transparent coating making PCB in insulation state from outside. And this coating saves that USB converter to burnt down by material short- circuit.
  • USB-to-serial RS-232 adapters are often use with consumer, commercial and industrial applications and USB-to-serial RS-485/422 adapters are usually mainly use only with industrial applications.

PL-2303HX highly compatible drivers could simulate the traditional.

COM port on most operating systems allowing the existing applications base on COM port to easily migrate and be made USB ready.

PL-2303 is exclusively design for mobile and embedded solutions in mind,

providing a small footprint that could easily fit in to any connectors and handheld devices,
