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.

That way I could pick the Arduino UART and mix it with the Hackaday PWM output module along with my own Verilog or VHDL. The way things are structured now you will have one bitstream that is ...

The APC220 header feeds power to the module on pins 1 and 2 (GND and 5 V) and connects pins 4 and 5 (UART) to Arduino pins 0 and 1. The APC220 module (see next image) has a total of nine pins (only ...

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 ...
