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.
