|Some of the retired Arduino products, more here.|
One product closer to my work is the Arduino Esplora. Many folks had praised the design, but not many projects came out. I published some of the first projects including the work on pin outs and compatible displays. Two things hampered the platform: the insistence of using the Tinkerkit inputs and outputs (which no one used in published projects), and the power requirement via a USB connection (when a battery power option would have been the way to go). The Tinkerkit issue has also plagued other retired projects including the Robot and the USB Host Shield.
If you look at new Arduino.cc offerings, you can see the evolution of Arduino products. New Arduinos consider LiPo battery use and using more affordable components like ESP8266 based wi-fi modules. Certainly the new MKR1000 board is a welcome addition. We are in for exciting times ahead. What are your thoughts?
