Description

The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to a max 2A/phase. It is based on the Allegro A4988 stepper driver chip. It's the next version of the popular Easy Driver board.


Each Big Easy Driver can drive up to a max of 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling while operating at 1.4-1.7A/phase, a heatsink is required for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.


Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to him for product support and continued development.


Feature：

  • Bi-polar Microstepping Driver
  • 2A/Phase Max
  • 1.4-1.7A/Phase w/o Heatsink
  • Max Motor Drive Voltage: 30V
  • On-board 5V/3.3V Regulation



Pin Descriptions

Several pins of the A4988 IC are broken out on the Big Easy Driver, allowing direct connection to a bi-polar stepper motor, as well as a microcontroller.


Board Top Pins

  • Coil A+: DMOS Full Bridge 1 Output B. Half of connection point for bi-polar stepper motor coil A.
  • Coil A-: DMOS Full Bridge 1 Output A. Other half of connection point for bi-polar stepper motor coil A.
  • Coil B+: DMOS Full Bridge 2 Output B. Half of connection point for bi-polar stepper motor coil B.
  • Coil B-: DMOS Full Bridge 2 Output A. Other half of connection point for bi-polar stepper motor coil B.
  • GND: Ground.
  • M+: Power supply. 8V - 35V.


Bottom Pins：

  • ENABLE: Logic Input. Enables the FET functionality within the motor driver. If set to HIGH, the FETs will be disabled, and the IC will not drive the motor. If set to LOW, all FETs will be enabled, allowing motor control.
  • MS1: Logic Input. Microstep Select 1 has a pull-up resistance of 20 kOhms. See truth table below for HIGH/LOW functionality.
  • MS2: Logic Input. Microstep Select 2 has a pull-up resistance of 20 kOhms. See truth table below for HIGH/LOW functionality.
  • MS3: Logic Input. Microstep Select 3 has a pull-up resistance of 20 kOhms. See truth table below for HIGH/LOW functionality.
