Connectors

Sort passive connector adapters from Qwiic boards, LCD modules and microSD card adapters before assuming anything with the right plug will substitute safely.

Passive power adapters

5.5 × 2.1 mm barrel

Use when the source and target voltage already make sense. These parts change the connector, not the electrical design.

Qwiic-connected boards

Qwiic · I²C ecosystem

Qwiic reduces wiring mistakes, but each board still has a specific function, firmware and address/library expectation.

General board checks (5)
  • Decide the job first: passive power adapter, Qwiic/I²C board, display module or storage-card adapter.
  • For barrel parts, confirm plug size, center polarity, source voltage and the receiving board's allowed input range.
  • For Qwiic boards, confirm I²C address, firmware/library support, host voltage assumptions and whether the board is the thing you actually want to replace.
  • For microSD adapters, confirm card size, slot orientation, clearance and the host device's supported card format.
  • Use the exact vendor page as the final source before buying or swapping.
