Simple step and direction control interface Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Can interface directly with 3.3 V and 5 V systems
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout Short-to-ground and shorted-load protection 4-layer, 2 oz copper PCB for improved heat dissipation
The drv8825 stepper motor driver carrier is a breakout board for ti’s drv8825 micro stepping bipolar stepper motor driver. The drv8825 features adjustable current limiting, overcurrent and over temperature protection and six micro step resolutions (down to 1 or 32step). It operates from 8.2 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling). This product is a carrier board or breakout board for ti’s drv8825 stepper motor driver; we therefore recommend careful reading of the drv8825 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the power dissipation considerations section below for more information). Here are some of the driver’s key features: simple step and direction control interface six different step resolutions: full step, half step, 1 or 4step, 1 or 8step, 1 or 16step and 1 or 32step adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to Achieve higher step rates intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) 45 v maximum supply voltage built-in regulator (no external logic voltage supply needed) can interface directly with 3.3 V and 5 v systems over temperature thermal shutdown, overcurrent shutdown and under voltage lockout shorttoground and shorted load protection 4layer, 2 oz. copper piece for improved heat dissipation exposed solder able ground pad below the driver ic on the bottom of the piece this product ships with all surface mount components—including the drv8825 driver ic.
