Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980?

The UNO R4 WiFi features Wi-Fi and Bluetooth Low Energy connectivity, while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer.

Details of Arduino UNO R4 32-bit board revealed, including the 12x8 RED LED matrix on board and connectivity for IoT applications.
