mCookies are Arduino and LEGO-compatible modules

These quarter-sized, stackable, Arduino and LEGO-compatible modules allow Makers to bring their ideas to life. 

If there’s one trend that is continuing to evolve throughout the Maker Movement, it’s modularity. DIYers are constantly seeking expedited and efficient ways to piece together their projects, all while bringing their ideas to life without the hassles of soldering and wiring messes. Joining the likes of littleBits and Modulo, the Microduino crew has launched mCookie — a small, stackable electronic hardware kit for designers, engineers and curious tinkerers of any age and skill set.


You may recall their first Kickstarter campaign from back in September 2013, which went on to garner well over its pledge goal in just a matter of days. Since then, Microduino has developed over 50 blocks and 30 sensors, and has granted users access to more than 100 basic tutorials, 500 project samples and a burgeoning online community.

Hoping to continue riding its wave of success, the next-generation of Microduino consists of quarter-sized hardware components inspired by the incredibly popular Arduino platform that not only connect magnetically, but can be built into predesigned projects or used to innovate new ones as well. Each open source module is color-coded and is designed to be stacked on top of a main processor to perform one core function — whether that’s expanding Bluetooth and Wi-Fi capabilities, GPS and sensor hubs, audio and battery management, or a core USB.


As its creators note, there are three microcontroller modules in the mCookie series, all of which powered by Atmel. The CoreUSB is built around the ATmega32U4, while the Core and Core+ are driven by an ATmega328P and ATmega644PA, respectively.

Ultimately, these components will provide users with the ability to build any number of projects, ranging from drones and robots to wearables and smart gardening gadgets. Helping speed up the development process, these devices can be programmed using Arduino IDE and integrated into existing Arduino sketches of all kinds. Aside from that, the modules are even LEGO-compatible and only fit together when the right connection is formed, making them more accessible to people of all ages and eliminating the need for soldering.

Meanwhile, for projects that require a little more reinforcement, spring pins offer rugged surface-to-surface linkage between circuit boards for an extended usable lifetime, and M2 screws can be employed to securely fasten more robust designs. Not only geared towards beginners, experienced and well-seasoned Makers can write their own programs in the Arduino IDE and transmit that program to the hardware via USB, too.


mCookie comes in a variety of packages, including Basic, Advanced and Expert kits, each of which bundles different boards and sensors. So whether you’re looking for a fast and simple way to devise a remote-controlled LEGO car, a Wi-Fi weather station or even a DIY quadcopter, mCookie is for you. With its incredibly popular crowdfunding campaign complete, Microduino expects to begin shipping units by the end of July 2015.
