Omega2 Pro Now Runs Node-RED

Hi, all. Further to our encouraging Omega2 Pro production update a couple of days ago, we’re back with an exciting new feature announcement: Omega2 Pro now runs Node-RED! This feature introduces a whole new range of possibilities for programming and developing with the Omega2 Pro.

What is Node-RED and why are we excited?

Node-RED is a flow-based, visual programming tool that runs in the browser. It comes packaged as an OnionOS App on the Omega2 Pro and can be easily accessed through OnionOS in any browser. If you’re not familiar with Node-RED, check out Adafruit’s explanation of what Node-RED is and how it works.

We’ve made Node-RED available on the Omega2 Pro because it’s a very useful and amazingly powerful visual programming tool. Whilst this is a distinct advantage for beginners, it’s also a real boon to experienced programmers to create useful and complex programs relatively easily. This is all made possible thanks to the additional storage and memory available on the Omega2 Pro.

Other reasons Node-RED will put a smile on your face:

  1. There’s a whole gamut of nodes available, allowing users to build

complex applications very quickly. 2. Programming with Node-RED is very productive, whether you’re a beginner or a seasoned professional. 3. Node-RED makes it really easy to go from logical program flow (read: napkin drawing) to a Node-RED flow. On top of that, it allows you to quickly iterate on your program, fixing mistakes and adding functionality. 4. Node-RED is very beginner friendly. There’s no need to worry about individual lines of code — the visual programming style makes it very clear what’s going on in the program.

How to Install and Run Node-RED

When the Node-RED OnionOS App is installed, your Omega2 Pro will host the application and it can be accessed through the browser of any computer on the same network as the Omega. Installing Node-RED is an absolute breeze using the OnionOS App Manager. Just navigate to OnionOS in your browser, login, and it will be available to install using the App Manager. Your Omega2 Pro will then automatically run Node-RED on boot, as well as any deployed flow you may have created.

We’re immensely excited about being able to run Node-RED with Omega2 Pro as it can seriously expand programming potential and help you bring projects to life in quick and creative ways!

Getting Started with Node-RED

Now is an ideal time to familiarize yourself with Node-RED while awaiting delivery of your Omega2 Pro. That way, you’ll be ready to start working with Node-RED when it arrives. Here are some tutorials to introduce you to the awesomeness Node-RED offers:

The end of the campaign and first shipment of Omega2 Pros is just a few short weeks from now! We’re sure quite a few of you are busting to get your hands on your Omega2 Pro just as much as we’re excited about rolling them out. We’re just getting this party started, so stay tuned for more exciting updates over the next couple of weeks.

$55

Omega2 Pro

An Omega2 Pro IoT Computer so you can get a head start on your projects in the new year!


$85

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.


$140

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


$15

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.


$15

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.


$20

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.


$15

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.


$5

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.


$15

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.


$35

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.
