The breakout board for the 8825 micro-stepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six micro-step resolutions (down to 1/32-step). It operates from 8.2 V to 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). The driver has a pinout and interface that are nearly identical to those of the 4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications, but firmware will have to be modified or updated.
Size: 1.5mmX2mm (same as 4988)
The maximum current is 2.5A.
The highest support for 32 subdivisions.
4-layer PCB board, better heat dissipation performance.
The chip’s internal resistance is smaller, lower heat, and better heat dissipation.
Driven current: 2.5A.
Subdivision: 1, 1/2, 1/4, 1/8, 1/16, 1/32
Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance.
Need to drive the stepper motor.
It is a necessary module for building 3D printers, CNC, engraving machines, etc.
Supported 3D printers are Prusa Mendel, Ultimaker, printbot, MakerBot, and so on.
