![]() ![]() The popularity of the Mega isn't as great as that for the Uno and similar 328 based boards - likely because of the DIP packaging if nothing else. Most have been documented, but I bet a few haven't. Then get a Mega and do some research on it, the ATMega controller used on it (read those datasheets!) - and see what differences there are. It has 54 digital input/output pins (of which 15 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. Ultimately - you should start out with the Uno - and get very familiar with it. 3 online today The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Many of these are clones, some of them quite good and reliable (for instance, Seeedstudio's boards are great quality, and most have desireable features not found on official boards - even the cloned Uno boards!). You might find this, for instance, with third-party shields from Chinese sellers - they may or may not know, or not care - but if you have this information handy - then you can be wary about it.Īs far as that VE shield is concerned, though - this is only really an issue with the "official" Mega - there are Mega clones out there which bring out -every- pin (there are others that aren't brought out to headers on the official board) to a header. There may also be other shields out there which are being sold as "works with the Mega" - in which the designer or seller doesn't actually know whether it does or not (or maybe they don't care - or maybe they do know, but they don't know why). Why?Įssentially, one of the pins that is required by the board - while it exists on the microcontroller used by the Mega (ATMega1280/2560) - isn't brought out to an actual pin on the board! Why? Who knows!īut if you didn't know that - you would think that shield would work. It will not work with the Mega or the Leonardo (or I suspect certain other boards). It will only work with the Uno, Duemilanove, and other similar variants (heck, it would probably work with one of the original ATMega8-based serial Arduino boards from the beginning - with attendant memory limitations). You can have a look at Crowduino Mega2560 ACA2560MEG Micro Controller Arduino Compatible in Elecrow bazaar! for more detail info about ATmega2560. The Mega 2560 is an update to the Arduino Mega, which it replaces. ![]() The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). ![]() Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. 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. The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). You can find in the Getting Started with Arduino MEGA2560 Rev 3 section all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.įrom the Tutorials section, you can find examples from libraries and built-in sketches as well as other useful information to expand your knowledge of the Arduino hardware and software.Well, the differences between Arduino Uno and Arduino Mega 2560 are as follow. Getting Startedįind inspiration for your projects with the Mega 2560 board from our tutorial platform Project Hub. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analogue inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The 8-bit Arduino board with 54 digital pins, 16 analogue inputs and 4 serial ports. ![]()
