Arduino Mega

Vendor's Description: 

The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

just found out about this and already cant wait to get one. Arduino is popular for its simplicity but this can be limmiting when getting into higher end projects. but finaly, it has come. with a whoping 54 (of which 14 provide PWM output) digital I/O's. and 16 analog inputs, the Arduino Mega is here. the improvements dont stop there, take a look at this...


Operating Voltage5V
Input Voltage (recommended)7-12V
Input Voltage (limits)6-20V
Digital I/O Pins54 (of which 14 provide PWM output)
Analog Input Pins16
DC Current per I/O Pin40 mA
DC Current for 3.3V Pin50 mA
Flash Memory128 KB of which 4 KB used by bootloader
Clock Speed

16 MHz

it has more of pretty much everything including 4 serial channels!
it does however come at a price, 40$ more than your standard arduino or picaxe dev-board. but in my opinion this board must offer the best mix of power and simplicity for the cash.

My Arduino Mega board arrived yesterday. First tests has been succesfull. You can use it like any other Arduino board, without or minimal changing existing code, just recompile it. Most of existing Arduino shields works on the Arduino Mega too, because of the same pinout. 

At the moment, I have no plan or time for a robot project with the Arduino Mega. :( 

i just bought a Arduino Duemilanove and i can´t wait to get it. do you know if there are any books on how to start programming the Arduino?
i know of only one book for beginners to arduino, its called " getting started with arduino " a quick amazon shearch should find it, its written the the inventor of arduino which is good. however i found the online references informative enough to get going.
okay thanks. i have found some internet pages so now i only need the arduino!!

Here is my ressource list for Arduino programming beginners:


great info
