Arduino peripherals, including Arduino shields, sometimes take up multiple I/O pins and leave little room to create a project that requires multiple Arduino peripherals.

The Arduino team explain more about the origins of the iconic Arduino UNO microcontroller “As familiar as we all are with the UNO, there’s probably a lot you don’t know about the iconic ...

Right now, the Ponte only supports Arduino Uno-sized shield, so the possibility of an all-in-one RepRap controller using the RAMPS motor driver is impossible for now.
