[Q] What are good upgrades from Arduino or Raspberry Pi? A more powerful microcontroller

Hello

Arduino is a good microcontroller for DIY and hobby projects. But when you are thinking of making something that has many actuators and sensors and requires very fast processing, then you would need to think of other alternatives. Also, Arduino is not multithreaded (not really a requirement for me).

So, what better microcontrollers that are not very expensive (1000$+) and is used in robotics?

I prefer something that is well supported and has a text-based programming language (Not LabView for myRIO for example).

For a faster processor, some people use a “Teensy” Teensy 4.1 Is the First Arduino-Compatible Board with 100 Mbit Ethernet · Coupled with a 600 MHz 32-bit.

You may also look at other AVR microcontrollers that have more I/O pins.

There are other companies that make micro-controllers, but they may not be programmable with tools (IDE) like arduino.
