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, as well as RX, TX, RTS and CTS at 3V logic levels. 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 / 5V Logic. The data signals are at 5V and the power line provides 5V. We suggest this for any product that needs FTDI cables and has 5V logic/power usage or is 5V-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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
