BreadShield is a shield that maps Arduino pins to breadboard ties without jumper wires. It inserts into both of them, firmly bridging them together mechanically and electrically.

What problems it solves

Many projects start with connecting an Arduino and a breadboard using jumper wires. But jumper wires can easily become too many to manage, forming a mess of spaghetti that is difficult to trace and debug. To disconnect the breadboard temporarily or to swap it, you have to undo and rewire it. This can lead to errors if you forget how the board was wired in the first place. And most importantly, since the sockets are occupied by jumper wires, you cannot use any shield boards!

Too mamy jumper wires can lead to a messy project that is hard to manage.

Shields and jumper wires cannot co-exist in one project.

Introducing BreadShield:

The Arduino shield for breadboards

Like you, we have suffered enough. One day we asked, what if all of those messy jumper wires could become one shield? So BreadShield was born. BreadShield maps standard Arduino Uno R3 pins to one row of pins that can be inserted directly into a breadboard.

BreadShield connects an Arduino Uno with an HD44780 LCD with only 1 jumper wire, instead of 11 parallel jumper wires above.

BreadShield Benefits

  • Have major Arduino pins on your breadboard instantly
  • Swap between breadboards swiftly
  • Never worry about messed up connections
  • No more tracking back-and-forth between the Arduino and the breadboard

No more choosing between shields or breadboards

You no longer have to make a choice between using existing shields and using a breadboard - with BreadShield, you can use both! And you can stack the shields as high as you want.

BreadShield vs. Jumper wires

BreadShield can be used in countless projects, thanks to the popularity of both Arduino and breadboards. It can even work with other hardware that is Arduino-compatible, such as HiFive1 Rev B.

Take a look at a few examples below. Aren’t the ones on the right tidier?

Auto-alignment of headers for easy soldering

Keeping the stackable headers upright is always a challenge when soldering an Arduino shield. It’s not a problem for BreadShield, which is the first shield that automatically aligns the header. We’ve carefully tuned the diameter of the pad holes to be slightly bigger than the pins’. Once inserted into the holes, the headers will stand up straight, or perpendicular to the shield, automatically. Since they remain in position (thanks to the friction) you don’t need to hold them using tools like a “third hand” or a “helping hand”. Just solder.

We will make our Github repo public with all design files, and our thoughts in interating the prototypes, as soon as the campaign concludes. So help us reach our goal! The world needs BreadShield.

Manufacturing Plan

We have been involved in making hardware, especially in Shen Zhen and Guang Zhou (Canton) in China, for the past decade. We also speak Mandarin, which is extremely helpful when sourcing parts and establishing relationships with manufacturers. We have visited Hua Qiang Bei in Shen Zhen several times. For this project, we obtained quotes from several PCB or PCBA manufacturers, and sourced the parts ourselves (Forrest would like to thank Hebi for finding a magic Chinese website called TaoBao), to ensure that you get competitive prices. We are connected with two reliable PCBA manufacturers in China. We plan to move forward with one. But if something happens, we will opt for Plan B with the other manufacturer so orders won’t be delayed.

Fulfillment and Logistics

We are not only production-ready, we are ship-ready!

We are ready to ship!

All orders will be shipped by Crowd Supply’s fulfillment service. Early orders (approximately first 100 kits and first 20 assembled) will be sent to Crowd Supply immediately after the campaign concludes (remember to keep your shipping address updated in your Crowd Supply account).

Remaining kit and soldered version orders will be shipped to Crowd Supply in two and four weeks, respectively. Once the packages reach Crowd Supply, it will take them one more week to forward your orders. Since it takes 3-4 days from us to Crowd Supply, early backers in the US may get your orders as soon as two weeks after the campaign ends.

As the campaign develops, we will pipeline orders in minibatches of 100 or 200 (depending on how fast the demand grows), and sent to Crowd Supply as soon as they reach us in Iowa. That will avoid the need for a big order at the end of the campaign with a very long lead time.

For more information on shipping, please see Crowd Supply’s guide on ordering, paying, and shipping and remember to keep your shipping address updated in your account. Tracking is included in all shipments.

Risks and contingency plan

There are no risks for the kit version (unassembled PCB and parts) because the connectors are commonly used and PCB manufacturing is quite standard, with lots of PCB manufacturers out there. The only risk is if we get an unexpectedly high number of orders for the soldered version. However, we have set the timeline reasonably to prepare for the worst, i.e., longest lead time. We have contacted several manufactures to ensure enough redundancy. The last resort is that we will manually assemble for you, our dear backers! Any delays will be communicated promptly and clearly through updates.

All products are sold as-is. We cannot promise any warranty nor technical support, although we will try our best to help you. We cannot handle returns due to mistakes in your address or government decisions. If your package is damaged, we will be happy to send you a replacement.

Team

We are based in Ames, Iowa. During the day, Forrest is a computer science professor. In our spare time, we like to build hardware together. This is our first hobbyist project, paid for by our own pocket money and evening/weekend time. Forrest has a Ph.D. in Computer Science (major) and Electrical Engineering (minor).

Don’t be dissuaded because this is our first crowdfunding campaign. We are serious people and have put in the time and research required for a successful campaign. Forrest regularly publishes at top AI conferences. He has been reported on/interviewed by MIT Technology Review website and Lancet Neurology. He is also a co-inventor of one US/PCT patent and two patent applications. We are committed to delivering BreadShield to Crowd Supply in the next 60 days (or 80 days for soldered version).
