Fully Funded & Hardware Details

First and foremost, a huge THANK YOU to everyone who has backed! With your support, we hit the funding goal on day 2 of the campaign! Now, a week after the launch, we’ve hit 150% of the campaign target. Just incredible! We’re very excited about the reception the Dash has gotten and we can’t wait to see the amazing UIs you all make.

A few details we’d light to highlight about the Omega2 Dash hardware:

  • The centerpiece of the Omega2 Dash design is the Omega2S module. Just like the

Omega2 Pro and Omega2 LTE boards that were launched here on Crowd Supply, the Omega2 Dash uses the Omega2S+ variant. It provides the CPU, 128 MB RAM memory, 32 MB flash storage, and the WiFi Radio. Visit our site for more information on the Omega2S modules.

  • Omega2S modules are available for purchase in volume directly from Onion

as well as our distributors Mouser and Digikey.

  • We've had a few questions about the longevity of the 3.2" TFT display. We're pleased to report that

it’s rated for a hefty 50,000 hours minimum MTBF (Mean Time Between Failures) under normal operation.

We’ll have more updates for you in the coming weeks. Stay tuned and tell your friends!

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.
