How to achieve micro usb to UART connection?
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
Hi,
Sorry for the newbie question, I am trying to achieve the UART connection as pictured below: https://wiki.dfrobot.com/Gravity:%20I2C%20&%20UART%20NFC%20Module%20SKU:%20DFR0231-H
What is the simplest way to achieve this connection?
Do I need a converter like this and then use a micro USB to micro USB cable? https://wiki.dfrobot.com/FTDI_Basic_Breakout_3.3_5V__SKU__DFR0065_
Or would I get the Adafruit USB A to TTL cable and then a USB A to micro USB converter?
Thank you!

I had a similar challenge and I just purchased a 5v output TTL converter and the work was done perfectly. You can try your luck too.
all the best

USB to UART converters or bridges present themselves as a serial port to your computer and send serial data over a couple of wires. They can be used to make a serial connection to another device. In this post we’ll look into how this works.

I assume that you intend to make PC talk to NFC. Any usb→ TTL converter will do the job. Just be aware of the voltage level.
