Difference between "bulk" and "no bulk" stepper motor driver?


2 differents type of stepper motor driver are sold :

  • bulk stepper motor driver
  • stepper motor driver

what is the difference between them ?

thank you in advance for your reply.

the schematic seems to be the same but it’s not representative of reality.
does this have something to do with bulk capacitance?


The bulk-packaged version of those stepper motor driver carriers require a minimum order quantity of five units. This option is intended for customers interested in higher volumes at lower unit costs.

Both versions are otherwise identical.
