Here will be answers to the most frequently asked questions regarding STM, Arduino, and OPI/RPI.

Which OS can be installed on Raspberry Pi/Orange Pi?

For single-board computers, there are many Unix-like operating systems available, mainly distributions like Ubuntu, Debian, and CentOS. You can also install Android and Windows (which is a bit more complex).

For Raspberry Pi, the most common OS options can be viewed in the Raspberry Pi Imager itself. For Raspberry Pi, there are even distributions of Android and special OSes designed for managing 3D printers.

The most common operating systems for Orange Pi can be viewed on their official website by selecting the Downloads section on the page of your Orange Pi version.
There are official distributions supported by the Orange Pi developers: As well as custom ones, they have lower stability, but can boast various features, such as a unique interface or a narrow specialization of the system:

How do Orange PI and STM32 work together simultaneously?

There are several ways to communicate between different microcontrollers. In our constructor, we use the UART (Universal Asynchronous Receiver/Transmitter) protocol, which is the oldest and most common physical data transmission protocol today.

Data transmission is achieved using a USB TTL UART converter. It looks like this: The Rx Tx pins are connected to the STM32, while on the other side there is a Mini USB connector that is connected to the Orange Pi. More details about UART can be found on our forum in the STM32 Tutorials.
