USB-C to TTL Cable Converter

I created this because my Arduino Nano microcontroller was not compatible with my computer. This cable bridges that gap.

I did not use any code for this project.

The materials I used were:

  • Arduino Nano microcontroller
  • USB-C port module
  • Wires
  • 5-piece DuPont connector housing
  • Plastic piece for tension
  • Tape labeled top

I began with taking my microcontroller and taking a USB-C port module.

Then I obtained wires. I connected them with my 5 piece DuPont connector housing. I used two holes in a plastic piece to keep it in tension and therefore mechanically secured.

I wrote on a paper all the connections and how I should solder them.

Once I soldered them, the tool was almost complete.

I added a piece of tape that says "top" to represent the top side of the wire connector. This makes sure that I connect this device correctly and I don't accidentally switch up ground and VCC.

I tested it with my shift register project.
