Typical module price range: RM18-RM45. 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.

Ground

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

Primary interface

Plan for SPI; confirm the exact terminal names in the manufacturer documentation.

Variant-specific connections

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