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 ATmega16U2/32U2 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 white 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 ATmega328P and ATmega16U2’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.

Note: The STEMTera is available for pre-order. We expect orders to start shipping very soon. Adding a pre-order product to an order may cause a delay. Be sure to uncheck “ship complete order” in your cart to avoid delays in shipping in-stock items.

  • ——————– Tech Support Tips/Troubleshooting/Common Issues ——————–

    Try looking at my comments posted here for Tips/Troubleshooting/Common Issues => https://www.sparkfun.com/products/14082#comment-588f7a5cf3b1a814268b4568 . It links to useful documentation and information about the STEMTera.

  • I just got mine stemterra today. It looks nice but came with no documentation. Can you provide a link to documentation on the board?

    There is a power plug but it doesn’t saw what voltage or polarity it is.

    Also, what does the usb port connect to? Can it be used for power?

    A schematic would be really nice.

    • Schematic, PCB, Fritzing, Firmware, 3D STL files and components datasheet is located here https://github.com/STEMTera/STEMTera-Breadboard-B328

      The USB port is used to connect to a PC for sketch uploading just like an Arduino and can also be used to power the board.

      The power jack polarity is embossed on the product next to the jack. Input Voltage : 6 - 20VDC (recommended 7 - 12VDC) just like an Arduino.

      The board works exactly like an Arduino UNO R3, and sketch or tutorial you can find online for Arduino UNO can be used. The official user guide is still on going and you can have early access here

      http://learn.stemtera.com

      and also download the source of the user guide from here

      Hope this helps. Feel free to drop a message here if you need other information.

      Cheers JP

      • Thanks, JP those links are a big help.

        I can’t believe I missed the embossed power spec. I need new glasses I guess.

        Just as a pointer to others looking for information here, there is another thread of comments under the black STEMTera board you might want to check out. Mostly the same information, but if you don’t see what you’re looking for here, check out the black STEMTera board description.

        Thanks, George

  • Oh wow. That is definitely amazing.

  • Is there a possible date on when you will have these in stock?
