A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project ... IDs and assigns each a virtual serial port. While this was a hack born of necessity ...

So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated hardware.

Arduino enthusiasts searching for an isolated USB to UART converter specifically designed for the Arduino Pro mini may be interested in a new piece of hardware created by Simone based in Italy.

The need for a second UART port ( and one that is not shared with USB) on the Arduino Uno is so great that the “SoftwareSerial” library in included in the Arduino IDE. It emulates additional ...
