Feather Battery I2C Shield For Particle and Feather Modules can be used  to provide cloud connectivity to a world of expansion controllers using this I2C shield and I2C expansion products. This shield includes a on-board power boost circuit which takes 3.3V from the battery and will boost it to 5V. This boosted 5V can be used to power up sensors or any other I2C modules we manufacture. The boost circuit is controlled by Feather IO pin A3. This will allow users to turn off the sensor while its not in use.  The power cut off feature makes it ideal for battery powered applications.

The Feather Battery I2C Shield provides a 5 Volt I2C expansion port, allowing your Particle Argon, Boron, Xenon or Feather Modules to connect to an ever-growing array of expansion devices from NCD.

Connect sensors for light level monitoring, gas level detection, temperature and humidity monitoring, as well as many types of motion, acceleration, and direction sensors.

Connect our entire array of relay controllers, digital I/O expanders, PWM controllers, and current monitoring devices to your next IoT application with a simple daisy-chain interface.

The FTHB_I2C provides a +5V I2C communication port, making it one of the most important expansions available. The Feather I2C Shield For Particle and Feather Modules allows you to easily handle the hardware side of IoT and automation so you can focus on the software.

This Feather Battery I2C Shield For Particle and Feather Modules has on board 3.3V to 5V I2C level shifter which makes it ideal it an ideal product to connect Particle Argon, Boron, Xenon or Feather Modules with I2C expansion products.

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.

+MORE App customizations

We partnered with Blynk who have developed the +MORE app.  If you are interested in customization to their +MORE app then we're sure you will enjoy working with them as much as we did.  They can customize the user interface +MORE mobile app at your request.

  • Add new functionality and features to the mobile applications and web dashboard
  • Change/ add data visualizations options
