Raise your micro-controller development skills to the next level with this MicroSD + FRAM Shield.

All updates for this shield will be posted at:

A Shield designed for the Spark Core
For Community, by Community.


What is it about?


This Shield brings you the best of both worlds; Mass Storage and High-speed RAM.

We designed it to be a simple Plug and Play module. All you need to do is snug this shield on and code away!


Practical Applications

Having 2 types of memory on a single Shield brings about interesting usage scenarios.

Here are some possible applications:

  • - Wireless Web server with media content
  • - Spark Core USB mass-storage device  
  • High speed Data-logging for mission-critical projects
  • - Smart Metering
  • Local database on microSD encrypted by FRAM 
  • Memory buffer for high-pixel LCD Displays


We <3 Open-Source!

All the Schematic design files and firmware Source code will be published on Github after crowdfunding.

This shield would not have been made possible without an AWESOME Open-source Community. We have benefitted tremendously and would love to continue supporting and embracing this development model.

The FULL functionalilty of this Shield will be tested before shipping to you. We will ensure that the entire FRAM memory space is Readable/Writable at the optimal transfer rate.

There are instances where the FRAM breakout modules solde in the Market that read/writes perfectly well for the front portion but fails at the end. We want to ship you the best product and testing is an important part of our manufacturing requirement.

Frequently Asked Questions

  • Why are you keeping to a low quantity manufacturing run?

    We believe in shipping on time and focusing on a small production run for our first pre-order will ensure this goal is achieved.

    A 2nd production run will be planned if there's sufficient demand!

  • Can we request for header-less shields?

    Totally! We know that some backers would like to solder the shield directly on their boards.

    Before shipping, we will confirm whether you want your shield with or without the headers on.

  • How much is shipping and are you making money out of it?

    The good news is, international shipping fees are INCLUDED in the pricing listed.

    We, ourselves, are crowd-funding backers too! It is discouraging to have additional shipping fees ranging from $5-$100.

    Therefore, the bare minimum to ship a Registered mail has been factored in and we absorb all the extra postage fees to deliver this shield into your hands.

    Feel free to back any of the Choices and we will handle the rest.

  • Can i purchase in bulk quantities?

    That's good to know! Drop us an email at and we will discuss offline.
