Production is Complete

by Lazar D

Omega2 Dash production is complete as of today!

What’s Next?

Now that production is complete, here’s what’s left to be done:

  1. The individual boards will be packaged
  2. Everything will be bulk shipped to Crowd Supply next week
  3. The Crowd Supply team will pick and pack the individual orders
  4. Shipping to individual backers is currently scheduled to start on May 4, 2020!

We’ve been working hard to make sure there’s minimal delays in getting the Omega2 Dash into your hands. But in these uncertain times, unforeseen issues can pop up and cause delays. In the event there are changes to the schedule, we’ll make sure to keep you informed.

We thank you for your patience.

A Look into the Manufacturing Process

Our manufacturing team has been documenting the Omega2 Dash production. Here’s how it looked:

Applying solder paste to the PCBs using a mask.

PCBs ready for the pick and place machine which will place all of the surface-mount components.

Coming out of the reflow oven - the solder has been melted and all of the components are now permanently attached.

Quality Control! Visual inspection using an automated optical inspection (AOI) machine to make sure all components have been properly placed.

TFT touchscreens waiting to be connected to boards that pass the visual inspection.

Screens being connected and immediately tested.

The testing program from last update. We brought the total up to 9 buttons to test more of the touchscreen.

Complete Omega2 Dash units ready to be packaged!

Another view. Every Expansion Header has a pin label - making it very easy to use the pins.

Product Choices


Omega2 Dash

An Omega2 Dash IoT computer. Perfect for making internet-connected control panels and user interfaces.


Ethernet Expansion

From the Onion Omega2 Pro project.

An Ethernet Expansion board for your Omega2 Dash

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

From the Onion Omega2 Pro project.

An NFC/RFID Expansion board for your Omega2 Dash

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

From the Onion Omega2 Pro project.

An ADC Expansion board for your Omega2 Dash

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

From the Onion Omega2 Pro project.

A Proto Expansion board for your Omega2 Dash

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

From the Onion Omega2 Pro project.

A Servo Expansion board for your Omega2 Dash

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.
