Malaysia Price Guidance

Cost

Typical module price range: RM5-RM15. This is component guidance only; a complete FYP cost depends on controller, sensors, casing, display, app/dashboard, documentation and timeline.

Connections

Connection overview

Module revisions can use different connector names and electrical limits. Treat this as a planning overview and verify the exact board marking, manufacturer datasheet and seller documentation before wiring.

Power

Use only a supply supported by the exact board or module variant. Common listings for this part mention 3.3V logic or 5V logic or 8V-35V motor supply.

Ground

Connect a common ground between the controller, module and any external supply.

Primary interface

Plan for STEP/DIR / GPIO; confirm the exact terminal names in the manufacturer documentation.

Variant-specific connections

Connector names and optional pins can differ between breakout-board revisions.

Platform Notes

Wiring Guides

A4988 with Arduino / ESP32

This is a planning overview, not a board-specific pin map. Confirm the exact module revision, supply limits and STEP/DIR / GPIO terminals in its datasheet before wiring. Use suitable level shifting when logic voltages differ.

Power	Confirm against the exact board; listed variants commonly use 3.3V logic / 5V logic / 8V-35V motor supply
Ground	Common ground with the controller
Interface	STEP/DIR, GPIO (exact pins vary by module)
