Legal Fabio, e eu consigo boa velocidade de avanco com ele? eles podem ser liagdos ao BOB?
Nessa fábrica Chinesa eles usam o MD882
* Patented technology

* High performance, low cost
* Supply voltage up to +75VDC
* Peak current to 8.2A (RMS5.86A)
* Optically isolated differential input
* pulse frequency up to 300 KHz
* Automatic idle-current reduction
* Suitable for 2-phase and 4-phase stepper motors
* 16 selectable resolutions up to 10000 steps/rev
* DIP switch current setting with 8 different values
* PUL/DIR & CW/CCW mode optional
* Short-circuit, over-voltage,short-voltage protection
* Small size (115x67.7x25mm)
Mas é caríssimo... e tem o mais barato da família que é o M325:
# High performance, low cost
# Supply voltage 12 to +24VDC,
Adjustable peak current 0.39 to 2.5A
# 3-state current control technology
# The current semi-reduction automatically switches in on absence of clock pulses CP
# Suitable for 2-phase and 4-phase stepping motors
# Optically isolated input signals
# Pulse frequency up to 100 KHz
# 4 Selectable microstep resolutions 1,2,4 and 8
# DIP switch current setting with 7 different values
* PUL/DIR & CW/CCW mode optional
# Clock Pulse and Direction Inputs feature photoelectric isolation
# Small size (86x55x20.5mm)
