Looking for recommendation ESP32 versus S2

Postby dfrenkel » Sun Feb 21, 2021 3:37 pm

We currently use an ESP32 to run our WiFi controlled stepper motor. The dual cores allow us to run the stepper motor on one core, and maintain a constant connection on the second core, and it all works very well.

I'm curious about the ESP32-S2. I realize it's a single core, but can the low power core be used to maintain the wifi connection so we can dedicate the main core to running the stepper motor which blocks all other code from running and cannot share tasks with wifi.

No, if anything you would have to do the opposite. But esp32 price has gone down too so probably just stick with it.
