Shipping Underway & Getting Started Guide

Hi everyone,

Wow! What a wild last couple of days of the campaign! With your support, the campaign came to a close at 412% of our original goal! A huge thank you to everyone who backed the campaign and shared it with their friends. We absolutely cannot wait to see what you make with your very own Omega2 Pro! On that note, we have some good news to share:

Shipping Has Started

On Friday, February 1st, we started shipping orders placed during the crowdfunding portion of the campaign. All orders are being processed through our fulfillment partner in the USA. If you backed the campaign during the crowdfunding period, expect an email from Crowd Supply with your tracking number in the next couple of days!

Once shipped, packages typically take 7-10 days to arrive to destinations in the continental USA. We’ve seen it take three weeks in extreme cases. For international shipments, expect two to three weeks.

Getting Started Guide

We figured you would want to get up and running as soon as you get your Omega2 Pro, so we’ve published an Omega2 Pro Getting Started Guide! The guide covers:

  • Using the browser-based Setup Wizard to connect to a Wi-Fi network
  • Updating the software to the latest version
  • Details on the Expansion Header
  • Connecting a LiPo battery and reading the voltage level
  • Controlling the full-color LED
  • Installing Node-Red

Follow the guide when you receive your Omega2 Pro and you’ll have all the tools needed to build a great project in no time.

Pre-orders Available

If you missed the campaign, the Omega2 Pro is still available to pre-order right here on Crowd Supply! There are only about a dozen available for shipping in February. All other pre-orders will ship in late March as part of our second production run.

Thanks again for a great campaign!

Product Choices


Omega2 Pro

An Omega2 Pro IoT Computer so you can get a head start on your projects in the new year!


Omega2 Pro Essentials Collection

An Omega2 Pro and our essential, most popular OLED and Ethernet Expansions. Build projects with a small physical display, that can use wireless or wired networking.


Omega2 Pro Ultimate Collection

An Omega2 Pro and the whole family of available Expansions: NFC/RFID Expansion, ADC Expansion, GPS Expansion, OLED Expansion, Servo (PWM) Expansion, Relay Expansion, Ethernet Expansion, Proto Expansion


OLED Expansion

The OLED Expansion adds a low-power 0.96″ monochrome display to your Omega. With a resolution of 128×64, you can use it to display text, images, and even animations. Very useful for displaying status information, web data, and small logos.


Ethernet Expansion

The Ethernet Expansion adds an Ethernet port to your Omega with a maximum connection speed of 100Mbps. While the Omega is all about wireless connectivity, a reliable wired network connection can be a great addition to a project, and the Ethernet Expansion is a great tool for quickly reflashing your Omega’s firmware.


NFC/RFID Expansion

Bring contact-less RFID and NFC communication to your Omega2. It supports reading and writing with several NFC and RFID protocols at 13.56 MHz. Comes bundled with two programmable Mifare Ultralight tags.


ADC Expansion

Omega2 can now read all types of analog voltages and sensors with the help of this ADC Expansion. Read and interpret up to 4 analog voltage or sensor inputs, each with 16 bits of precision.


Proto Expansion

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.


Servo Expansion

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. The Servo Expansion is often also called the PWM Expansion.


Omega2+ Expansion Dock

From the Omega2+ Expansion Dock project.

An expansion board that gives the Omega2+ IoT board access to various modules, sensors, and USB devices through SPI, I²S, I²C, UART, USB 2.0, and Ethernet. Also provides a real-time clock with dedicated battery power.
