Hi all, another newbie here.
Did the OP ever get anywhere with this? I think I might have the same driver board from www.doit.am and cannot get my 28BYJ-48 stepper to do anything with it.
I'm connecting the wires as OP but am also providing 5v from external source to the board and motor (while disconnected from USB). I see the NodeMCU led blinking as I've set it in the code, so I know that my code is running ok, but nothing happens to the motor.
I'm also looking to write my code with Arduino IDE much rather than with LUA but am clueless what the Stepper (or AccelStepper) pinouts should be for the driver board.
Stepper motor itself seems ok based on testing the coil pairs with a led.
Any help much appreciated.
