The Arduino 9V Battery Connector with DC Jack connects a 9V battery to Arduino boards via the DC barrel jack. It provides portable power for Arduino projects without requiring a wall adapter.
Key features
- 9V battery clip connector
- 5.5mm x 2.1mm DC barrel plug
- Center positive polarity
- Approx 15cm wire
- Portable power solution
- Plug-and-play with Arduino
- Low cost
Good to know
- 9V batteries have limited capacity – use for low-power projects
- Battery voltage drops with use – may affect analog readings
- Remove battery when not in use to prevent drain
- Consider rechargeable 9V NiMH for repeated use
- For longer runtime, use 6xAA battery holder instead
