I'm new with electronics and with udoo neo and i have a question about stepper motors. Do i need a stepping stepper motor driver like the one in the image bellow to make it work? I'm trying to make a CNC from an arduino uno project and that project uses three stepper motor drivers so i want to know if i need those having the Udoo NEO board or if the board bring that on the board (i don't understand too much the "9-axis motion sensors" that are embedded). This is the project i want to make
The Arduino side of the Neo does not have a stepper module *Edit* like all other Arduino's don't have a stepper module. So you will need one. The 9 axis motion sensor is a sensor that measures movement of the board itself. It cannot drive motors. You can use this for example when you mount your board on a robot, drone or segway clone.
@waltervl Thanks for your response! Another question.. what do you mean with "...a stepper module like all other Arduino's"? you mean that there is an arduino that came with a stepper module? Regards, Gonzalo.
Hi, you must isolate motor power from UDOO power so a driver is mandatory. You can use 4 NPN MOSFETs, an ULN2003 (Darlington) or a driver board like the A4988 or the DRV8825. You will need to use 4 pins on your board (6 if you want to enable microstepping) plus 5V and GND. Here's an example:
