Their downside is that theyre very slow (0.3 revolutions/second max), and only suitable for light-duty applications. The advantage of these motors is that they are inexpensive and easily available on Amazon. These motors are very small with a built in gear reduction. So at least I got all the information summarized. This Arduino library is used to control one or more 28BYJ-48 stepper motors. Moving the EN to the right spot - the one on the edge solved a week of me-pulling-my-hair-out. Here few links to the stepper driver: Silent2209 - FYSETC WIKIĪccording to the description on the board I though the EN pin is the the second one from the edge but this is the MS1. I can confirm, that the ESP32 is running, I can see the "High"/"Low" messages in the serial console, I was able to blink the internal LED (the commented out code).
