USB to UART cable with 5V TTL level UART signals. 6 output wires terminated by a 6 way 0.1 Single-In-Line (SIL) connector6 way outputs provide Tx Rx RTS# CTS# VCC and GND. Data transfer rates from 300 baud to 3 Mbaud at TTL levelsConnect directly to a microcontroller UART or I/O pins. 5V TTL output allows external logic to be powered from the USB portReplace MAX232 type level shifters allowing for direct connection of products to PC via USBFT232R chipset provides single chip USB to asynchronous serial data transfer interface. Works with all Windows and Mac OS versions.
