It lets you run two bipolar stepper motors independently for precision motion control in robotics, CNC machines, or automated camera rigs. On‑board current‑adjustment potentiometers and five microstep modes give you full control over torque and positioning.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDriver Chip\u003c\/td\u003e\n\u003ctd\u003eDual A4988\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMotor Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e8 V – 35 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLogic Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3 V (from Raspberry Pi)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMax Current per Coil\u003c\/td\u003e\n\u003ctd\u003e2 A (adjustable via potentiometer)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrostep Resolution\u003c\/td\u003e\n\u003ctd\u003eFull, 1\/2, 1\/4, 1\/8, 1\/16 (jumper-selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e65 × 56 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-motorised-camera-slider\"\u003eMotorised camera slider for time‑lapse photography\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-2-axis-cnc-laser-engraver\"\u003eSmall‑format CNC plotter or laser engraver\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eDesktop 3D printer or filament winder\u003c\/li\u003e\n  \u003cli\u003eRobotic arm with two‑axis position control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe HAT fits any Raspberry Pi with a 40‑pin GPIO header: Pi 4, Pi 3, Pi 2, Pi Zero (with header), and Pi 5. It works with all bipolar stepper motors rated up to 2 A per coil and 8 V–35 V. Common pairings include NEMA 17 motors and 12 V or 24 V power supplies.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003ePlug the HAT directly onto the Raspberry Pi’s GPIO pins. Connect your motor power supply to the screw‑terminal block (8 V–35 V, center‑positive) and attach stepper motors to the M1 and M2 terminals. Before running, set the drive current by measuring the reference voltage on each potentiometer; the A4988’s step, direction, and enable pins map to standard GPIO lines.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi 5?\u003c\/summary\u003e\u003cp\u003eYes. The HAT stacks onto the 40‑pin GPIO header of the Pi 5. You may need to install libraries such as RPi.GPIO or pigpio, which are fully supported on the Pi 5.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat type of stepper motors can I use?\u003c\/summary\u003e\u003cp\u003eAny bipolar stepper motor with a coil current rating up to 2 A and an operating voltage between 8 V and 35 V. NEMA 17 motors are a common choice.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the board need an external power supply?\u003c\/summary\u003e\u003cp\u003eYes, a separate DC power source (8 V–35 V) must be connected to the screw terminals for the motors. The Raspberry Pi’s 5 V rail cannot supply the required motor current.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
