Choose Your Adventure

Have an awesome electronic widget that you want to get to market? Great! We are always listening to new ideas from our customers and the community. We get many inquires on this topic, so read this tutorial carefully to keep your product pitch from getting lost in the shuffle.

We’re lucky, here at SparkFun, to have an amazingly creative and talented group of customers. Not only can they identify gaps in the catalogs of electronics suppliers, they can create a gizmo that fills that hole. But, going beyond a prototype or even a limited-quantity production run, often the hardest task in getting your world-alterring product out there is producing, marketing, and/or selling it to the masses. That’s where we come into the picture. We recognize that there comes a certain benefit to having your product in our catalog and we want to give you the best chance to have that. However, the partnership needs to make sense for both parties (maybe more parties) involved.

We strive to keep the SparkFun catalog of products curated. A selection of products that help get your project completed that we would use ourselves. So regretfully we cannot take all products brought to us. Below we have outlined what we look for, how we can possibly work together, and the steps to take in order to properly submit your product for evaluation.

SparkFun aims to sell parts and boards pertinent to DIY electronics. This may touch on areas relating to education, prototyping, and product design. Among the reasons for stocking certain products, we look for things that are helpful, cutting edge, useful in a broad spectrum, and appealing the community. We want products that make things easy for the user, but at the same time, do not constrain the possible uses for the product.

Over the years SparkFun has helped to bring dozens of unique widgets and useful electronic shortcuts – dreamt-up and designed by our customers – to the throngs of electronics hobbyists, artists, and students. We’ve gone through this process enough to know how to guide any product through it. The goal of this tutorial is to walk you through two of the most common routes previous collaborators have followed in getting their widgets sold on SparkFun. Which route you choose mostly depends on who is manufacturing your product. Time to choose your adventure.

Option 1: You Manufacture, SparkFun Buys and Resells

Have you already set up a manufacturing process for your design? Whether you’re cooking the boards in your basement reflow toaster, or working with an established assembly house, we might be interested in reselling it. What really matters is that you have a solid, tested design, a manufacturing process set up for it, and a market starving to buy it.

Hundreds of products in the SparkFun catalog go through this process, including:

It’s the fastest route to our storefront, if that’s what interests you the most. Check out this half of the tutorial to find out more about how to pitch your product.

Option 1: You Manufacture, SparkFun Resells

Option 2: SparkFun Manufactures, and Pays You a Royalty Per Sale

Have you prototyped your design, and proven that it works, but gotten stuck trying to produce and sell it? Well it just so happens that we have pick-and-place machines, reflow ovens, and a all-star production team that can help with manufacturing. Plus, our engineers can help polish the design along the way.

The best part about this option is you still get paid. Instead of buying the products up-front, we pay you a percentage-based royalty per product sold.

We do have limited production and design resources, so there’s no guarantee that we can take your product on. But if it’s unique enough, and fits within our manufacturing abilities, we’re certainly interested in working with you to help productize your widget. Here are few examples include:

Lilypad Pieces

WAV Trigger


These products have all gone through this process, and are now some of the highest-selling, most important products in our catalog. Check out this section of the tutorial to learn more about how to pitch your design.

Option 2: SparkFun Manufactures, You Get a Royalty

So, it all begins by figuring out who’s producing the widget. Read on to learn more about each option. At the end is a form you can use to submit your project/product/idea for review. Please read the entire tutorial before submitting as there is very pertinent information involved.

Option 1: You Manufacture, SparkFun Resells

This option is great for those who already have the resources to support manufacturing. In this relationship, SparkFun assumes the responsibilities of storefront management, inventory storage, shipping, and customer service. You, on the other hand, deal with manufacturing and assume all the risks inherent to that. This allows you to have more control over your product (revisions, pricing, documentation, etc).

A great example of this relationship in action is the pcDuino.

pcDuino 3

The pcDuino is designed and manufactured by our friends at LinkSprite. They support a community, publish the documentation, and handle all manufacturing, but aren’t as interested in hosting a storefront. So we resell it! As a bonus, the end-customer can save on shipping (or get it for free) when resistors, batteries, switches, and other components are inevitably added to the order.

Division of Responsibilities

Here’s an overview of who does what in this relationship:

SparkFun’s Responsibilities

To help store, sell, ship, and market your product, we have a great group of talented employees canvassing a wide variety of skills. Here are the roles we’ll take sole ownership of in the relationship:

Your Responsibilities

Shared Responsibilities

This is still a team effort. You’ve got a product that you love and want to see in the hands of as many users as possible. And we want to help get the word out and move some product! Here are some duties we might share in our quest:

Crowdfunding? Crowdfunded?

Kickstarter and Indiegogo

Many products in our catalog were born out of a crowdfunding website, like Kickstarter or Indiegogo. We’re happy to work with you, if your product is on this path, but there are a few caveats.

If you aim to approach us with a crowdfunded product, it’s best to do so after it’s been funded, or at least while it’s on a trajectory to be funded. But, most important of all, we need to know ahead of time how far out your product is from shipping. Obviously this is a sticking point for a lot of crowdfunded projects.

If your product failed to meet its crowdfunding goal, we might be able to work together to still make it a reality. Check out the next page to see how we can collaborate to produce your widget.

GroupGets + SparkFun = GetSparked!

Have an existing product already that you plan to sell in SparkFun's catalog but it requires a high minimum order quantity? Try collaborating with GroupGets to get something cheaper in volume by working with others and selling to a group of buyers.

GroupGets is a type of crowdfunding platform for hardware developers to test their prototypes in the market. Developers launch a “campaign” on the GroupGets site, and instead of receiving financial donations like Kickstarter, supporters of the product place an order. When a certain amount of orders are placed, GroupGets helps that developer run a small batch of their product. They are a crucial step in the startup process for entrepreneurs in the hardware space because they facilitate a connection between those entrepreneurs, the customer, and small batch manufacturing.

If your product performed well on GroupGets in terms of sales and user feedback, they connect you with SparkFun for the next steps on how to get into our online catalog. For more information, check out the button below.

Option 2: SparkFun Manufactures, You Get a Royalty

This option is great for those looking to steer clear of the hassles of organizing manufacturing and generally running a business. We’ll keep in contact with you about further revisions or changes to your design, but we deal with the manufacturing risks. We buy the parts and the PCBs to build your widget. We monitor demand and order stock to meet it. Doing this we can often significantly reduce the cost of the BOM (bill of materials), and produce a reliable, steady supply of your widget.

An example of this relationship is the WAV Trigger. The hardware and firmware was spearheaded by Jamie Robertson with one of our engineers guiding the design to help leverage the SparkFun manufacturing process.

We generally prefer Open Source Hardware designs for this relationship. Almost always those designs will be published under the creative commons license, so please take a look and decide if this is ideal for you. For more information check out some of these related posts:

Division of Responsibilities

Our load is much heavier in this relationship, but we still need some help from you. Here’s an example of what we’ll be doing, what we expect from you, and what duties we’ll share in:

SparkFun’s Responsibilities

Your Responsibilities

Shared Responsibilities

Collaborative Design Process

Since we’ll be the ones manufacturing the board, there are certain design-for-manufacturability adjustments we usually like to make in order to keep costs down and production times minimal. These changes include:

To help implement these DFM adjustments, one of our talented engineers will be assigned to work with you on bringing it in house. No matter what, we’ll work and communicate with you along the way to make sure our changes don’t alter your vision of your product.

As a result of the “design scrub”, this option takes longer than the previously mentioned route. We’ll go through at least one prototype round of the design to iron out any production issues, and just make sure the thing works as intended. If you want to get a head start, and make things go a little more smoothly, try design your product to follow as many of our design rules as possible. Check out the next page for more details on that!

Designing for (SparkFun) Manufuacture

The schematic and PCB designs are the heart of most SparkFun products. Over the last 10+ years, we’ve designed hundreds of unique PCBs, and produced millions of widgets, so we know what adjustments to the design will make our production process flow as smoothly as possible.

Those adjustments have found their way into a loose set of rules that we know to follow, but you might not. Designing your product with these rules in mind will give you a head start, and it’ll also make your product pitch more attractive to us. The less work we have to put into scrubbing your design, the faster we can start building and shipping it!

PCB Design Specifications

In as many designs as possible, we try to keep our board layouts within this set of specifications:

PCB minimum specs

EAGLE Design Rules

Further to those minimum specifications, here are some more EAGLE-specific design rules:

Make sure to load the Sparkfun.dru for the DRC check. Pull the most up-to-date version of the Sparkfun.dru from GitHub. Don’t use the default settings!

PCB Aesthetics (Labeling)

When the bare PCB is your product, it doesn’t hurt to dress it up and make the board look nice and polished. Here are some EAGLE-specific design rules that we follow to make our boards look as good as possible.

Pitching Your Product

Pitching a product can be a daunting task. In order to make it easier for you, we have a guide for the information we need below. Please, when pitching your product be as informative as possible. The information we get from this email will be a strong indicator of whether it is something we would be interested in. Below is an explanation of the different questions to address in your email:
