Production Has Started

by Lazar D

We’re pleased to report that production of the Omega2 Dash has started! Omega2 Dash units and collections ordered during the campaign on Crowd Supply will be ready to ship on April 30th, 2020. (Pre-orders will begin shipping after all campaign orders have been filled). We’ll share photos and updates as production progresses.

Testing Program

To make sure the touchscreen on each completed Omega2 Dash can display images and detect touch input correctly, we’ve made a small testing program to be used as part of our testing and QA process. It’s based on our LVGL Quickstart Template and uses the Omega2 platform’s USB auto-run functionality to speed up testing.

As part of the QA process, workers will plug in a USB drive pre-loaded with the test program into the Omega2 Dash. The test program will run automatically (thanks to USB auto-run), and will show this on the display:

The worker will then touch all 5 of the "Press Me" buttons, with the expectation that the program will respond to each touch input and change the color and text of the buttons:

Any units that don’t display the test program correctly or don’t show 5 OKs after testing will be marked as failed, and will be closely inspected to see what went wrong.

The source code and binaries for the test program can be found on Github.

We thought you would enjoy this small insight into our manufacturing process. Until next time!

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.
