<!-- TITLE: Powering the Atomic Pi --> <!-- SUBTITLE: Power requirements and specifications --> # Powering the Atomic Pi According to Digital Loggers, the Atomic Pi should be provided at least 5V at 3A to function properly. The power is provided via headers at the underside of the board. For easier connection, two breakout boards are available that add either screw terminals or a barrel jack for convenience. **Breakout Board for Atomic Pi:** ![Breakout](/uploads/breakout.jpg "Breakout") **Baby Breakout for Atomic Pi:** ![Baby Breakout](/uploads/baby-breakout.png "Baby Breakout") **What's the difference?** ***The Breakout Board provides the following:*** 1. A terminal block to easily apply 5v and 12v. NO 2.5mm DC Barrel Jack. 2. A USB serial interface for debugging the Atomic Pi. (Not for power.) 3. A series of terminal blocks to allow easy access to the Atomic Pi's GPIO. 4. An extra USB 2.0 port for the Atomic Pi. 5. A prototyping area for custom electronic additions. 6. A special area for soldering an Arduino Nano, which can connect to the Atomic Pi. ***The Baby Breakout Board Provides the following:*** 1. A 2.5mm DC Barrel Jack for Easy Powering. 2. A small selection of broken out GPIO pins. 3. An area to apply 12v so the built-in 10W analogue speaker amp can function. In addition to the 5V system voltage, a separate 12V at 1A can be provided for the built-in 10W analogue speaker amp (optional and not needed for digital audio out via HDMI). > Todo: add annotaded images of board connector, breakout boards and PSUs {.is-info}
