ESP32 Board for High-Speed Stepper Motor Control

[jonas22]

Hello Community,

I'm currently working on a project that involves controlling stepper motors at high speeds using an ESP32 board with built-in WiFi. However, I'm facing issues with the ESP32 WROOM 32 Dev Module, as it is unable to run the motors properly alongside WiFi communication.

I'm now looking for recommendations on the most powerful ESP32 board that can handle high-speed stepper motor control while maintaining reliable WiFi communication. Any suggestions or insights into boards that have been successfully used for similar applications would be greatly appreciated.

Thank you in advance for your help and advice!

How many?
What is "high speed" to you?

Try and use a hardware peripheral for the signal generation instead of "bitbanging" in software.

As mentioned, use a hardeware peripheral to generate the step pulses:

Also use a stepper driver board such as A4988 (cheap) or DRV8825 (more features) for fancy functionality such as micro stepping and current ramping.
