Power Dock 2 for Onion Omega

Added to your shopping cart

The Power Dock 2 allows you to use any 3.7V LiPo battery to power your Omega and then charge the battery when it’s out of juice. Utilizing the same form factor as the Expansion Dock, this board also can be used in the same way, so if you don’t have a battery connected you will still be able to receive power through the microUSB port.

The Power Dock breaks out the Omega’s GPIO pins so you can use them to control external circuits or connect expansion boards to extend the functionality of your Omega. The Power Dock 2 adds an ADC that allows the Omega to measure the voltage level of an attached LiPo battery. This will give you a better idea of how much juice is left in the battery!

The Onion Omega boards we carry are separated into three different categories: Mainboard, Dock and Expansion Board. This board falls into the Dock category, meaning you can plug an Onion Omega directly into the board. The Expansion Dock is also compatible with Omega Expansion Boards, making it one of the most straightforward docks produced by Onion.

  • JST-PH LiPo Battery Connector
  • ADC to measure LiPo battery voltage level
  • MicroUSB Port – Power and Battery Charging
  • USB-A Port – Connect USB devices to the Omega
  • Reset Button
  • Power Switch
  • 30-pin Expansion Header

Power Dock 2 for Onion Omega Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Customer Comments

  • Is it possible to dock the ethernet Expansion with the NFC Tag simultaniously? Can’t find any informations about stacking up.

  • I use my battery dock with a 3.7v 2500mAh Lithium Ion Polymer Battery (About $15) and it lasts 12 to 20 hours depending on what I’m doing and which expansions I’m using. You do lose the USB serial with this dock, so be careful when experimenting with Wifi networking modifications on the go, you might not be able to ssh in to fix it.
