NOTE: My store has moved

You can now find these items in my Etsy store.

This is a blank (bare) PCB for building an open source split-flap display controller. Once assembled (electronic components must be purchased separately), it plugs into an Arduino Uno as a shield, allowing the Arduino to control 4 split-flap modules.

Or, if you've already built a control board and are looking to expand your split-flap display, you can build up to 2 more of these control boards and chain them together. See this note for more info.

This board is designed to use almost entirely through-hole components, so this is great for people with intermediate experience soldering.

Note: The "COMMIT" and "DATE" labels on the board may vary from what's shown in these product photos.

Thinking about building a split-flap display?

Make sure to check out the ordering instructions which explain how to order the necessary electronic components for this PCB and everything else that makes up a complete split-flap display. Once you've ordered everything, check out the tips on how to put everything together.

So why am I selling just a bare PCB?

It's simple: high fixed costs of PCB manufacturing make small/low-quantity orders expensive. I want my splitflap project to be accessible to lots of hobbyists, but ordering a PCB can be daunting and unless you're planning to build 40 splitflap modules, you probably don't need/want to pay for a whole batch of 10 or more PCBs if you just need 1 or 2.

I've ordered a bunch of these boards so that I can make them available to you in small or single quantities for a reasonable price. I just want to make it easier for you to order one or two. You can alternatively download the gerbers from the project website and send it off to your PCB manufacturer of choice by following these instructions.

What about the electronic components? Why don't I sell those too?

Great question! I may add an option in the future, but it adds complexity on my end so for now I wanted to make these PCBs available since I already have them in stock. To purchase the electronic components needed to assemble this board, please see the v0.5 Ordering Instructions document
