Microstepping Bipolar Chopper Stepper Motor Driver Kit (55Vdc, 3 Amp) * Open Source - The schematic, parts list, and software are all freely downloadable! * Hobbiest-friendly - No surface mount parts means allows this drive to be easily repaired! * DMOS driver chips rated at 55V and 3 Amps. * DIP Switch selectable modes of stepping: * Optically isolated step, direction, & enable signals. These signals are ground referenced so no +5VDC is required - hook directly to your parallel port. * Selectable automatic idle current reduction to reduce motor heating. Motor current can be reduced if no steps are recieved for 3 seconds. Oscilloscope Image * DIP switch selectable motor test mode. Allows for testing of motor/drive/wiring without an externally generated step signal. * Motor braking can be activated when drive is disabled. Alternatively, motor braking can also be disabled such that the motor will freewheel when drive is disabled. * Motor current is adjustable by two potentiometers. (One for each motor phase) * Removable screw terminals for all wiring connections. * Status LED flashes during normal operation to let the user know the microcontroller is running. Illuminates solid during a fault condition. * Quality double-sided printed circuit board with ground plane and silkscreen legend. Board size is 3.25" x 4.30" with mounting holes for #6 screws in each corner. For schematics, parts list, design notes, AVR firmware and etc. please visit this website. Please contact me if you need more than one drive, and I will be happy to list larger quantities. (please look at our rules and privacy policy) |
