DC Power Adapter Module for Breadboard — 5.5×2.1mm Jack to 2.54mm Header
A compact DC power adapter module that converts a standard 5.5×2.1mm barrel jack DC input to 2.54mm breadboard-compatible header pins. Power your breadboard circuits directly from a DC wall adapter without a separate voltage regulator. Ideal for powering Arduino breadboard projects from a bench power supply or DC adapter.
Key Features
- ✅ 5.5×2.1mm barrel jack input — standard DC adapter connector
- ✅ 2.54mm header output — plug directly into breadboard power rails
- ✅ Polarity protection — reverse polarity indicator LED
- ✅ Compact design — minimal footprint on breadboard
- ✅ RoHS compliant
Typical Applications
- Powering breadboard circuits from DC wall adapters
- Arduino breadboard power supply
- Electronics lab bench power distribution
- Sensor and module power supply prototyping
