EZSync FTDI chip usb to 3.3v TTL UART serial cable, wire end, 1.5m, TTL-232R-3V3-WE compatible, EZsync006 USB to UART cable with +3.3V TTL level UART signals. Wire ended output allow most flexible connection Connect directly to a microcontroller UART or I/O pins. +3.3V TTL output allows external logic to be powered from the USB port Overmolded FT232R chipset provides single chip USB to asynchronous serial data transfer interface. Works with all Windows and Mac OS versions 6 outputs provide Tx, Rx, RTS#, CTS#, VCC and GND. Data transfer rates from 300 baud to 3 Mbaud at TTL levels Replace MAX232 type level shifters allowing for direct connection of products to PC via USB
