Connections
Connection overview
Power
Use only a supply supported by the exact board or module variant. Common listings for this part mention 3.3V or 5V.
Ground
Connect a common ground between the controller, module and any external supply.
Primary interface
Plan for Analog / Digital; confirm the exact terminal names in the manufacturer documentation.
Variant-specific connections
Connector names and optional pins can differ between breakout-board revisions.
