Cable Usb Adaptador Conversor Usb A Ttl Pl2303hx 3.3v Blanco Uart Itytarg

Características: 

• • Conversión de USB a interface de transmisión asíncrona serial de datos UART
  • Cable con IC PL2303HX de Prolific, pines de conexión hembra
  • Acceso a señales GND (Negro), VCC (Rojo 3.3V +-10%, se puede desoldar y soldar 5V desarmando el chasis), TX (Verde) y RX (Blanco)
  • El protocolo es manejado por entero en el chip, no se requiere programación de firmware específica para USB
  • OTPROM interna para almacenar ID y descripción del producto
  • Buffer de datos bidireccional configurable de 512 bytes
  • Drivers para Windows, Mac, Linux y Android gratuitos, eliminan la necesidad de desarrollar drivers para la aplicación en la mayoría de los casos
  • La interface UART soporta 5, 6, 7 y 8 bits de datos, 1, 1 1/2 ó 2 bits de parada, y paridad par/impar/marca/espacio/sin paridad
  • Velocidad programable de 75 bps a 6 Mbps
  • Compatible con USB 2.0 Full speed
  • Longitud 1 m aprox.
  • Si se utiliza para descargar sketch's al Arduino se debe pulsar el reset del Arduino y mantenerlo mientras compila, entonces soltarlo apenas se muestre "cargando"

PL-2303HX USB to Serial Bridge Controller

The 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. The PL-2303HX highly compatible drivers could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port to easily migrate and be made USB ready. The PL-2303HX is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily fit in to any connectors and handheld devices. With very small power consumption in either operating or suspend mode, the PL-2303HX is perfect for bus powered operation with plenty of power left for the attached devices. 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.
