Description: The STEMTera is an innovation in breadboard history. It is the first breadboard with an Arduino-compatible hardware suite built in that works with thousands of shields. With ATmega32U2 pins exposed, native USB projects can be easily developed using the LUFA framework. The STEMTera also features a LEGO® brick-compatible bottom that empowers projects to be built beyond imagination. This version of the STEMTera is housed in a durable black ABS plastic enclosure.
Since the STEMTera is a development board built directly into a breadboard, it eliminates the need for messy wires to be strewn about your work space. By having two microcontrollers built inside the breadboard, it provides direct access to the ATmega328P’s I/O pins. With the 21 I/O pins of the ATmega32U2 exposed, users will be able to develop native USB projects with ease. These extra I/O pins can work directly with the LUFA framework without having a middleman to translate messages as with the original Arduino UNO. Additionally, the STEMTera is pin-to-pin compatible with an Arduino UNO R3 shield and supports multiple IDEs, including: Atmel® Studio, Arduino IDE, AVR-GCC, AVR-GCC with LUFA, Scratch and more!
The STEMTera even has a LEGO-compatible 10x14 bottom cover that enables LEGO bricks to be connected directly into the breadboard without using special mounting techniques or adapters.
Dimensions: 111.8mm x 79.8mm x 16.1mm

Ok, I pre-ordered this thing because it’s basically what I want to use in teaching non-technical artists physical computing. I’ve been working with Arduino since 2006 or so and this is one of the best concepts I’ve seen teaching.
“comma but” it loses a point for what should be a trivial manufacturing defect. (I come from consumer electronics where we sold millions of devices with USB ports…)
The micro USB connector is flaky as hell on mine. I have to wiggle it just right to get a working connection. I’ve tried every micro USB cable I can find and they all work the same – prop the STEMTera up on something then wiggle/support the cord until there’s a good connection.

I got it on time. Worked out-of-box. Plugged in a 1Sheeld+ and proceeded to use my Nexus sensors. Way Cool. But, I was wondering about something. How about getting rid of the second controller and using the space for internal Lipo’s with 5v or 3v toggle and rechargeable circuitry on board. Then it’s a real “Unplug-N-Go” project. Or standalone as some might say. In any case, I like it.
By the way, what IS the real purpose of having that second controller anyway??? Am I missing something???
Found it… LUFA (Lightweight USB Framework for AVRs) Good stuff to know. Check’m out below.
Another quick thought as to its use. Like I did. Make it talk to the kids cellphone. That will get their attention and hold on to it. HEY!!! Put a Simblee as the second processor… Yeah, that’s the ticket!!!
Tried to plug in my 2.8'‘ TFT Touch Shield v2.0. NO GO!!! Yikes, I didn’t consider the ICSP header. The TFT has the female header but the male header pins normally found on the UNO are not available NOR considered into the form-factor of the breadboard. Interesting.
Really like that it is self-contained.
It’s so convienent having an Arduino built into a breadboad.
Worked right from the beginning. I didn’t need to install anything, just selected it as an Arduino Uno in the compiler and it uploaded perfectly. I would like it if it used mini USB instead of micro USB since I am so used to the RedBoard, but otherwise I really like it
The Atmega328P uses an “Arduino Uno” bootloader. Make sure that you select the correct board definition when uploading.
For diagrams and getting started with the STEMTera™, Try looking at the STEMTera™ Breadboard Beginner’s Guide located here => http://learn.stemtera.com ].
Note: The user guide is on going development and the designers of STEMTera™ are adding pages as we go.
Try browsing the STEMTera™ GitHub repository for Schematic, PCB, Fritzing, Firmware, 3D STL files and components datasheet located here => [ https://github.com/STEMTera/STEMTera-Breadboard-B328 ].
Testing the STEMTera™ board and viewing it in the device manager, it looks like the ATmega16U2/ATmega32U2s use the USB-to-Serial drivers like the Arduino Uno. You will need to install the drivers as indicated here => [ https://www.arduino.cc/en/Guide/ArduinoUno#toc3 ]. If an Arduino Uno’s driver is already installed, your computer should automatically install and recognize the board. Plugging the board into my computer, the STEMTera™ was recognized the as the Arduino Uno and the drivers from memory worked.
SparkFun has not tested the ATmega16U2/ATmega32U2 using the LUFA (Lightweight USB Framework for AVRs) USB Bootloader and the chips additional features as stated in the kickstarter. I would assume that you might need a different driver after reflashing the avr chip with the LUFA [ http://www.fourwalledcubicle.com/LUFA.php ]. However, it looks like they have linked the LUFA Demos in the STEMTera™ GitHub repository here => https://github.com/STEMTera/STEMTera-Breadboard-B328-LUFA-Demo-Project .
