Convert any USB port into a serial port at TTL level with this handy adapter. Ideal for communicating with temporary or permanent circuits in an extremely simple way through a port.

Currently a great majority of devices such as dvd, tv, routers, switch, cell phones , hard drives, have a serial port at TTL level (Transistor Transistor Logic), it is very useful to reinstall or reprogram the device without the need to dismantle the eprom memory in which the instructions, operating system or firmware, basic for the equipment to work, are stored.
