Just about all electronics use a UART serial port with RX and TX pins for debugging, bootloading, programming, serial output, etc. But it’s rare for a computer to have a serial port anymore. Thus, a serial cable is an essential part of any electrical engineer’s toolkit.

This is a USB C to TTL serial cable with an FTDI FT232R usb/serial chip embedded in the head. It has a 6-pin socket at the end with 5V power and ground, and 3.3V logic (5V compatible) RX, TX, RTS and CTS. Useful whenever you want to communicate with a TTL serial device such as an Arduino Pro Mini or ESP breakout, and the pinout will match up exactly to any ‘FTDI’ 6-pin header.

The version we have is the 5V Power / 3V Logic. The data signals are at 3V output and the power line provides 5V. The logic pins are 5V-friendly so we suggest this for any product that needs FTDI cables and has 5V power usage or is 3V-logic friendly.

If you have a device that is running at 5V logic and power, this cable will work fine. If you want to tweak the voltages and signals a little, you should also check out the FTDI friend.

We also carry a 3V Power / 3V Logic FTDI Cable.

• Datasheet

Just about all electronics use a UART serial port with RX and TX pins for debugging, bootloading, programming, and serial output, but it is rare for computers to have a built-in serial port. This FTDI Serial TTL-232 USB Type C Cable provides a convenient USB-C to TTL serial connection with an embedded FTDI FT232R USB/serial chip.

The 6-pin socket includes 5V power and ground along with 3.3V logic (5V compatible) RX, TX, RTS, and CTS signals, making it ideal for communication with TTL serial devices such as Arduino Pro Mini or ESP breakouts. The cable outputs data signals at 3V with 5V power line and supports 5V-friendly logic pins.

Featuring a 1-meter long 28AWG cable, the wiring is as follows:

• Black – GND
• Brown – CTS
• Red – VCC 5V @ 500mA
• Orange – TXD 3V logic level
• Yellow – RXD 3V logic level
• Green – RTS

It is a perfect tool for engineers who need a reliable and easy-to-use serial cable for devices requiring 5V power and 3.3V logic levels.
