HRB8825 Stepper Motor HAT For Raspberry Pi

The HRB8825 Stepper Motor HAT is a top - notch solution for Raspberry Pi series boards and Jetson Nano. It can drive two stepper motors with up to 1/32 microstepping, making it ideal for 3D printers, sculpturing machines, and mechanical arms. It features a standard Raspberry Pi 40PIN GPIO extension header. With onboard dual HR8825 motor controller ICs having a built - in microstepping indexer, it's super easy to operate. There are 6 available microstepping modes configurable via DIP switches: full - step, half - step, 1/4 - step, 1/8 - step, 1/16 - step, and 1/32 - step. You can adjust the motor drive current using a potentiometer, with a maximum output of 2.5A. It comes with protection features like Overcurrent Protection (OCP), Thermal Shutdown (TSD), and VM Undervoltage Lockout (UVLO). An integrated 5V regulator allows powering the Raspberry Pi. There are multiple connector options for different stepper motor specifications. Development resources and a manual with examples in BCM2835, wiringPi, and python are also provided. The motor controller is HR8825, with a motor drive voltage of 8.2V - 28V, a motor drive current of 2.5A, a logic voltage of 3.3V, a mounting hole size of 3.0mm, and dimensions of 65 × 56mm.

Using the HRB8825 Stepper Motor HAT is easy. First, connect it to your Raspberry Pi or Jetson Nano through the 40PIN GPIO extension header. Then, connect your stepper motors to the appropriate motor interfaces on the board. You can set the microstepping mode using the DIP switches according to your needs. To adjust the motor drive current, simply turn the potentiometer. When powering the module, make sure to use an 8.2V - 28V DC power supply at the external power supply interface. You can also choose whether to power the Raspberry Pi from the module using the motor power switch. Remember, the Raspberry Pi and stepper motors shown in the reference pictures are not included. As for maintenance, keep the board clean and dry. Avoid exposing it to extreme temperatures or humidity.
