Take your IoT development into overdrive with the Omega2 Maker Kit. It includes everything from the Starter Kit and the Relay, Servo, and OLED Expansions, our three most popular expansions!

Build the same circuits as in the Starter Kit AND conduct 8 additional experiments using the Onion Expansions, including how to control servos, use an H-bridge to control a DC motor, write text and images to the OLED display, and control other high-powered circuits with the Relay Expansion.

Step by step instructions for building each circuit and running through each experiment can be found in the online Maker Kit Guide.

Jump-start your IoT development with the Omega2 Starter Kit, it includes everything you need to create 8 circuits that will teach you how to control LEDs, read inputs, control and read external sensors and displays, learn Python, and much more.

Step by step instructions for building each circuit with the included parts can be found in the online Starter Kit Guide.

Each Kit includes an Omega2+, an Expansion Dock, and a variety of electronics components that belong in the collection of every student of IoT, all nicely packed up in a stylish plastic carrying case.

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. It has the same form factor as the Expansion Dock and can also be used in the same way: no battery and receiving power through the Micro USB port. The 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 Proto Expansion for the Onion Omega allows you to create your very own expansion that interfaces with your Omega. It provides a small soldering area and 30-pin header that plugs into the Expansion Dock. With it you will have full control over what kind of project you design for your Omega.



The Relay Expansion enables your Omega to control two other, independent electrical circuits. The circuits are isolated from the Omega and can operate at much higher or lower voltages than the Omega. So you can control other circuits you’ve built or small household appliances rated up to 60W. This Expansion is perfect for home automation projects since it gives you the ability to control other devices remotely using your Omega.



The Servo Expansion adds 16 PWM (Pulse Width Modulation) outputs to your Omega. Connect standard servos directly to the Expansion since each channel has its own 3-pin connectors, making it that much easier to get started with your project! This Expansion is great in any application that requires servos, like a robotics project or anything with moving parts. Given that PWM is so useful, you can also use this Expansion to precisely control LEDs or drive a DC motor using an H-bridge.
