The Ultimate Arduino Mega 2560 Hardware Manual is from the same author and the table of contents is about the same as in the first book, but of course tailored to the Mega 2560 board. One difference ...

Hi, I am using GT-U8 gps module from here to interface with Arduino Mega 2560 R3. It needs a logic level converter and I am using TXS0108E 8-Bit Bi-Directional Logic Level Converter. I am using pin 19 ...

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They n… ...

An Arduino Mega controls the hand with the aid of two PCA9685 PWM drivers. The physical hand itself is made out of 3D-printed PLA and nylon, painted gold for a more striking appearance.

Chuck Todd has built a Arduino compatible Mega2560 expansion RAM that will enable those using the Arduino platform who need more that 8k RAM in the Arduino processor.

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.
