Product Description

This product is very similar to our USB - UART Converter, but based on a different IC with expanded functionality. It is a highly reliable IC that approaches the quality of FTDI chips.

One of the greatest advantages it has over the USB - UART Converter is the DTR pin. This pin can control the reset line of microcontrollers, allowing seemless uploading. For example, connecting the module's DTR pin to the DTR (sometimes labelled GRN) pin of the Arduino Pro Mini alleviates the need to hold down the reset button while uploading sketches.

This module can obviously also be used as a simple UART converter.
