Title: Advice on designing hardware interaction between an MCU and a host for beginners
Post by: rayan on September 16, 2023, 11:57:27 am

I am a beginner in electronic design and I am currently learning to read datasheets and draw schematics . I am interested in designing hardware interaction between an MCU and a host. Could you please advise me on some key considerations, such as voltage compatibility? Are there any resources available for beginners, or a complete guide to designing electronics for beginners?

If the MCU and 'host' can be the same SBC, you might look at the Raspberry PI 4 and, ideally, one of the starter kits.  The PI acts as an MCU in terms of wiggling pins and working mechanical things but it also runs Linux which provides a high level interface with code written in high level languages like Python, C or even Java.

There's quite an education in these kits and all code is provided

The Raspberry Pi 4B is extra (I would go for the 8GB variant).  You need a monitor (HDMI), keyboard,  mouse (USB) and microSD card (128 GB).

You could also consider the Pi 400

This setup allows very high level control of the IO pins.  You could set up the Pi with a Berkeley server socket and control the Pi from anywhere on Earth.  You might need a hole through your firewall for a specific IP address in order to reach the Pi from beyond the LAN.  But it's doable...

This is so ill-defined it smells of being LLM output.
