Production Update and Hardware Details

Greetings all Omega2 Pro enthusiasts and campaign supporters!

As we enter the 2nd week of 2019 we’re pleased to report that everything is moving forward nicely with the first Omega2 Pro manufacturing run.

In our December 18th update we reported that we’d started production of the first 500 units. We are continuing to maintain steady production and confident that we can start shipping out the first units as of January 31st. We’ll of course keep you updated and let you know the day that shipping commences.

Current production update: The current production status is very encouraging and overall the process is going very well and according to schedule.

  • The Omega2 Pro Printed Circuit Boards (PCBs) have been produced and

tested, and no defects have been found!

You can see just how smart the PCBs look:

You’ll notice that there are 6 copies of the same board on a single sheet, this is common practice to make the SMT process more efficient and increase the number of boards produced per minute of active machine time. During the manufacturing of the PCBs, channels are cut along the board borders on the sheet, so that the individual boards can be broken apart after the SMT is complete and the solder cools.

What’s next:

  • Our next stage of production is PCB Assembly, which involves

permanently affixing electronics components to the PCBs. This of course is a very important part of the production process which, given the stringent quality control production process, we’re highly confident will result in an optimum outcome.

Completion Process:
After PCB assembly is completed over the course of the next week, we’ll then be moving onto testing and Quality Control which is going to be very exciting. Stay tuned for coming updates on our progress with that.

Some Further Hardware Insights:
As many of you will already know, the Omega2 Pro design is open-source. The designs are available under the MIT license and can be found on GitHub.

  • The Omega2 Pro design is based around the Omega2S module. To

be precise, the Omega2S+ variant is the centerpiece of the Omega2 Pro, providing the CPU, 128MB RAM memory & WiFi radio. Visit our site for more information on the Omega2S modules.

  • Both the Omega2S and Omega2S+ modules are available for purchase in

volume directly from Onion or from Mouser

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.
