Production Complete

Hi everyone,

You’ll be pleased to hear that, as we approach the last week of January, our production is going well and according to schedule. We’re really pleased with the results and are happy to share some of the process photos with you.

PCB Assembly Successfully Completed!

Those of you who have been following our updates will recall we started the first production batch in mid-December. The next stage was the production of the printed circuit boards (PCBs), which was a complete success with zero defects found in any of the PCBs. This then paved the way for PCB assembly, which is now complete, as you’ll see from the images below!

The above video shows pick and place of electronics components in progress. The next stage, which is not pictured, is where the boards were passed through a reflow oven to melt the solder and permanently attach the components.

What’s next?

Our next step is to package the individual Omega2 Pro units and then ship in bulk to our US fulfillment partner. In turn, our fulfillment partner will, and this is where you can start getting very excited, ship directly to backers starting on January 31st! You will receive a shipping confirmation email with a tracking number from Crowd Supply when your order ships. You can see the status of your order by logging in to your Crowd Supply account.

Overall Status Summary

  1. All production is now complete and we are absolutely delighted with

the results. 2. We’re completely on track to start shipping this batch of 500 units to backers on January 31st. 3. Backers are still joining the campaign as the excitement builds. A very big thank you to everyone who has supported our project and also shown enthusiasm in sharing it with others.

We’re looking forward to bringing you another update as we edge toward the end of the campaign on January 31st.

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.
