Arduino Experimenting Shield 2.0

Same functionality, better display options

Arduino Experimenting Shield 2.0
Arduino Experimenting Shield 2.0
Labs Project
Based on a Labs project | September 2017 | Find it here
In the 2014 July/August issue of Elektor we wrote about our Arduino Extension Shield that, in particular for the Arduino Uno, provided additional interface options, LEDs, pushbuttons and an LCD. The shield enjoyed — and continues to enjoy — a great deal of interest. Time for a makeover! The Arduino Experimenting Shield 2.0 offers largely the same features as its predecessor, but, after 3.5 years, quickly revisiting the specific details can do no harm.

Materials

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.

Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
