It includes a souped-up Arduino-compatible board that can sink higher currents
Anyone teaching kids; Do you use handouts, pre-made sketches they can modify, or do you let them learn it bit by bit, until they are able to develop the program themselves?
However the onboard 5V regulator is much different: it is a switchmode power supply and with external power like 12 volts the board can supply 2 Amps at 5 volts (compared to about .5 Amps by the UNO).
This allows the user to directly plug several Servo motors directly into the 3-pin connectors on the board, or operate up to 16 relays on Relay driver boards, or supply many other devices that need 5 volts.DISCLAIMER: Mentioned stuff from my own shop...
