This pololu A4988 stepper motor driver is installed in a very largme amount of DIY 3D printers. It can be considered as the reference stepper driver amount stepper drivers. Courant dmaximum de bobine: 1.75A Max avec dissipateur. Max Current per coil: 1.75A
Allows to drive Stepper motors. Max coil current: 2.2A More powerfull and more precise than the commonly used A4988 Needs a good air flow below the chip THe heatsink is optional if you have a good air flow, but needed in order to use the max current. Maximum resultion of 1/32 micro-steps supported by 8bit micro-controlers such as Atmega 2560.
Expansion board for Stepper Drivers Compatible with : DRV8825, A4988 Switch for micro stepping configuration power supply pins : +5V / +12V /+24V Control pins: Enable, Direction, Step Compatible with Arduino, Raspberry Pi, Ramps 1.4, ARM, etc....
Ultra quiet stepper motor Drivers LV8729 High Qaality Compatible and replaces the well known A4988 and DRV8825 stepper motor drivers More silent and smooth than a A4988 Can reach up to 1/128th micro stepings Compatible with most standard controler boards Ideal for 3D printers, CNC, laser cutters, Hot wire machines
