EZsync FTDI Chip USB to TTL Serial Cable for Rapsberry Pi, 3.3V, TTL-232R-RPI Compatible, Debug and Programming Cable, EZSync012 This serial cable is designed for use with the Raspberry Pi (RPi), an ultra-low cost, Linux based miniaturized computer. It can also be used as a generic serial cable for any application requires USB to TTL communication Entire USB to TTL(3.3V) protocol is handled by the electronics circuit overmolded in the cable USB terminal. 3 pieces "flying leads" connectors provide GND(Black), TXD(Orange), RXD(Yellow) signals. Data transfer rates from 300 baud to 3 Mbaud at TTL levels. On board FTDI chip has configurable internal EEPROM. High output drive option allow I/O pins drive up to three times the standard signal drive level. UART signals can be individually inverted by configuring the EEPROM. Industry most reliable FTDI chip set & device drivers for maximum compatibility. Works with all Windows and Mac OS versions.
