Description

HRB8825 Stepper Motor HAT For Raspberry Pi, Drives Two Stepper Motors, Up To 1/32 Micro-stepping.HR8825 is a dual H-bridge motor driver chip that supports 32 subdivisions. It also integrates short-circuit, overheating, under-voltage and cross-conduction protection circuits, which can detect fault conditions and quickly cut off the H-bridge, thus providing protection for the motor and driver chip.
VM is the input voltage, the input range is: 8.2V to 45V, the input range of the integrated voltage regulator chip is 8.2V to 28V.
n SLEEP needs to be kept high, otherwise the chip will directly enter sleep mode, the H-bridge of the device is disabled, the charge pump circuit stops working, the V3P3 output is disabled, and all internal clocks stop working, and all logic inputs are ignored.

Feature:

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Onboard dual HR8825 motor controller IC with built-in micro stepping indexer, drives two stepper motors, easy to use
