Have you ever wanted to try using a flexible PCB in your project but just haven’t gotten around to it? 

Well this is your chance! Want free flexible circuit boards?

You don't have to build something to win. Show us what you want to design.

  • You can present your design on Fritzing
  • You can draw a block diagram on paper
  • You can design a full schematic/PCB

Digi-Key has partnered with Hackaday to provide the opportunity for 60 contest winners to receive 3 flexible circuits of their design! We will have 60 flexible designs (within 2 square inches or 13 square centimeters), manufactured with help from @oshpark and shipped directly to the winners! 

If your project is larger, we'll cover the first 2 square inches plus shipping, and you can cover any additional costs.

Flexible PCBs can have useful applications: their thinness and flexibility allow them to fit in places where rigid PCBs and wires might not work, and can reduce the overall weight of a project.

The only thing we ask is that your PCB design pass Design Rule Check (DRC) testing. Beyond that there are no limits - flex PCBs can be used in wearables, costumes, toys, flip-phone attachments, things with sensors, and so much more.

Some useful resources: OSHpark Flex PCB FAQ, Brian Benchoff's Creating a PCB In Everything guide. The following examples are included for inspiration, but may not meet this contest's requirements: Crawling PCB Bot, Flashy Business Cards, Flexible Battery Meter & Flexible PCB Speakers.

How to Enter 

Show pictures of your creation and tell the story of how you designed and built it by documenting it as a new project on Hackaday.io. Once you have published your project, look in the left sidebar for the "Submit project to..." menu in order to enter it in the Flexible Circuit Contest:


Project must have a PCB that has passed Design Rule Check (DRC) testing. Once designed, the PCB is sent to OSHpark, our trusted PCB manufacturer.

Judging Criteria

Beauty is in the eye of the beholder. That said, here are some criteria judges will have in mind while reviewing entries:

  • Creativity: Is the concept of your project interesting and unique?
  • Functionality: Is your circuit functional? Does it work?
  • Backstory: How well has the story been shared about how this was conceived and built?

Flexible Circuit Contest Rules:

  • Contest runs 7AM PST on Wednesday, March 6th, 2019 through 7AM PDT Wednesday, May 29, 2019 (here is a countdown timer).
  • Sharing schematics, source code, and/or design files is highly encouraged (but not required). These will be considered during judging and are a big part of "backstory" and helping us understand your flexible...
