In this third instalment, we complete the notes on the application testing that we developed to verify the performance of the Arduino Uno R4, including the extra boost provided by the use of the ESP32-S3.
As already discussed in the previous articles, there is a Minima version of the Arduino Uno R4 that does not include the ESP32-S3 (a powerful ARM microcontroller); we avoided this limitation by adding an external ESP32-S3 device, facing a challenging issue on the power lines.
Arduino Uno R4 multicore
I recall the architecture of game systems and arcade boards from the ’80s and ’90s, which operated multiple processors coexisting on the
