  • Interface Adapter with USB for Onion Omega for IoT Applications (Type A)
  • Adapts Onion Omega for Direct Interface to NCD Products
  • USB Interface for Programming Onion Omega


SKU: PR32-1 UPC: 689860064683 Categories: , ,


This adapter was designed to connect the Onion Omega WiFi module to any of our Particle Electron IoT devices.

This adapter includes a Level-Shifted I2C Communication Bus and a USB interface for programming the Onion Omega. This adapter is compatible with the OOKF Key Fob Receiver Shield for Onion Omega.

This adapter maps the I2C and Power connections only.




Adapter Types:

We have designed 3 types of adapters for Onion Omega to better suit the subtle size differences between controllers.* The vast majority of devices are compatible with the Type A adapter. Type B and C are for special-use cases. While Type C is also compatible with most devices, Type B will have fitment issues with many controllers, though it may be useful in certain circumstances.
Type A: Brings the Onion Omega to the front of the PCB with a bias to the right side, allowing taller components to peacefully coexist on the left side of the adapter.

Type B: Brings the Onion Omega to the front of the PCB with a bias to the center and slightly to the right, allowing taller components to peacefully coexist on each side of the adapter.

Type C: Keeps the Onion Omega 0.200″ from the front of the adapter, and is horizontally near center with a slight bias to the right.

*Please contact us if you are unsure of the adapter to use for a particular device. WE WILL CONTACT YOU IF YOU HAVE CHOSEN AN ADAPTER THAT DOES NOT FIT A CONTROLLER ON THE SAME ORDER.

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required.
