。Description。USB C is quickly becoming more and more prominent in the maker community because， let's be honest， who likes trying three times to insert USB into a port? This FTDI cable is a USB C to Serial converter which allows for a simple way to connect TTL interface devices to USB. Each 26AWG cable is one meter in length with the USB C side protected by a 2in enclosure.。The FTDI cable is designed around an RS232， which is housed in a USB C connector. The other side of the cable is terminated with a 0.1" pitch， 6-pin connector with the following pinout：RTS(Green)， RX(Yellow)， TX(Orange)， VCC 5V(Red)， CTS(Brown)， GND(Black). This FTDI to USB C Cable is also capable of handling high voltages up to 300V max.。There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators， but requires a Mini-B cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.
