New Features in the ProtoSnap Plus

Clear, Visual Layout — The silver traces connecting LilyPad boards together to illustrate their electrical connections are a key feature of the ProtoSnap series. The new LilyPad ProtoSnap Plus includes easy-to-follow traces for students to use as a guideline for their design projects before breaking them apart and during programming lessons. In the LilyPad Development Board, many of these traces were hidden or difficult to see and point out during a lesson.

LilyPad USB Plus — Many users prefer the LilyPad USB over other formats and have been asking for an update to the Development Board to include one. SparkFun's product team created the LilyPad USB Plus with added features including a built-in RGB LED and LED bar graph, as well as two additional power (+) and ground (-) sew tabs for ease of use.

Updated Labeling — Each sew tab on the LilyPad USB Plus includes a symbol (~) at the center indicating PWM capability or analog-to-digital converter (ADC) for quick reference for users during prototyping. This eliminates the need to look at documentation or datasheets while teaching and building. These labels are also included on the bottom of the LilyPad boards. The labeling extends to board names clearly beside the hardware on the ProtoSnap board for quick identification when teaching or exploring.

More LEDs — One of the most compelling early activities when learning to program is to create blinking light patterns with Arduino. Students can create quite complex programs using just an LED and their imagination. The LilyPad ProtoSnap Plus replaces the five white LEDs and tri-color LED offered on the original LilyPad Development Board with four pairs of colored LEDs (yellow, red, blue, green), an RGB LED, and six white LEDs in a bar graph configuration. Building the RGB and white LEDs onto the LilyPad USB Plus microcontroller freed up sew tabs to connect other LilyPad boards and eliminated additional sewn connections.

Expansion Ports — To increase flexibility of the new ProtoSnap Plus, four expansion ports were added that allow students to explore different sensor and output options not available pre-wired on the board, including I2C boards.
