Stepper motor driver [L6208]

thingiverse

This project is actually a fully functional stepper motor driver board. The design is based on L6208 chip which allows operation of stepper motors with supply voltages from 8 to 52 V and resulting current of up to 2.8 A. A small heatsink and general approach to form better conductive pattern are used to eliminate the need of active cooling of the chip and to provide better electrical noise immunity within the limits of L6208 chip. This solution was designed for and is actively used in Black Mamba Desktop CNC Mill: http://www.thingiverse.com/thing:128100 Provided design files are for Eagle CAD V6.5.
