There’s a new line of Arduino products out and we have stock! First up is the Arduino Uno R3 which adds a few interesting features and is a preview of future Arduinos to come. There has been a few changes the board is still compatible with all the older Arduino shields. However, the new version has added a few extra pins. The SDA and SCL pins are now moved next to the AREF. In addition, two pins are added by the RESET pin. One of which allows shields to adapt to the voltage provided by the board. In addition, the reset button has been moved by the USB jack and the ATmega8U2 gets upgraded to an ATMega16U2 for more memory.
Next up we have the new R3 version of the Arduino Mega 2560. The changes are essentially the same as with the Uno. The R3 adds a few new pins, changes the position of the reset switch, and now uses an ATMega16U2 instead of the 8U2.
