<![CDATA[stepper motor]]>Hi all
I am new to m5stack
I am working on a project where I need to use 12 stepper motor, so what I need to know is, can I add four step motor modules(Stepmotor Module with MEGA328P (DRV8825)) to the m5stack core and control each motor individually

is any manual available how to flash those hex files to the stepmotor module? Can´t the Firmware be flashed over serial?

If you do that then technically you could program multiple stepper modules in UiFlow as it allows you to set the i2c address in the blocks. I cannot say for sure though as I don't have any stepper modules on me to test with

And after reprogram them in Arduino ide can I then use UIFlow to program the robot
