Description

Arduino Mega 2560 Rev 3 (Official)The Arduino Mega 2560 is designed for more complex projects. With 54 digital I O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This gives your projects plenty of room and opportunities.

The Arduino Mega 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This gives your projects plenty of room and opportunities.

Rev 3 of the Arduino Mega 2560 has the following upgrades:
1) 1.0 pinout: SDA and SCL pins - near to the AREF pin - and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the board that uses ATSAM3X8E, that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
2) Stronger RESET circuit.
3) ATmega 16U2 replace the 8U2.

The Arduino Mega 2560 does not use the FTDI USB-to-serial driver chip used in past designs. Instead, it features the ATmega16U2 programmed as a USB-to-serial converter.

Note that this is the official version of the Arduino Mega 2560. While the price is higher than the clone boards, you can be sure of the reliability and compatibility of this official board with your computer & project.

Great dog toys

These are long lasting, durable dog toys. My dogs love the squeak sound.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...
