I need to make a 6 DOF Robotic Arm with Stepper motors and encoders. Which MCU board should I choose for it?
The board should have more than 34 GPIOs and should work well with Micro-Ros.
The Nucleo144 board looks suitable for you.
It has 144 PINs, Cortex-M4 and supports Arduino.

This could be a choice, it’s stm32 based like the necleo boards but comes with 8 modular step stick controllers and spare io

What if I use 64 pins Nucleo board which is not present in the Micro-ros supported board list.
Will it work with Micro-ros?
Will there be any drawbacks if it works with Micro-ros?
It looks like STM32F103 Nucleo which has 20KB RAM.
The memory size is too small to run micro-ROS.
How about Nucleo F411?
I found one locally available version NUCLEO-F767ZI. Please check this if its fine with Micro-Ros.
Actually, I cannot order directly from the official website because They are not delivering in Pakistan.
Yes, you can use that board.
