![]() This makes the Mega more compatible with projects that require more programming space. But in terms of programming space, huge differences abound the Uno is equipped with a programming space of 32kB while its colleague the Mega2560, is four-time its size at 256kB. Voltage, Program space and Clock Speed: Both the Arduino Uno can be powered with a voltage output of 5 volts and they share a similar clock speed of 16MHz.Talking about inputting information, the Arduino Mega is equipped with 54 input and output pins with 16 of them serving as analog inputs while the Uno spots 14 I/O pins and 6 analog pins. Both boards can be powered via USB and their USBs can also be converted to serial thereby making USB programming possible. Power and Digital Pins: In terms of how to power both boards, the Uno and Mega share some common features.This is a massive upgrade to the Uno’s Mega328 making it approximately four times more powerful than the Uno. Taking a look at the Arduino Uno, this most popular of boards are powered by the ATMega328 while for the Mega2560, its name connotes the microcontroller that powers it the ATMega2560. ![]() It is important to note that the Uno comes in two types through-hole and the SMD version-which uses either a through-hole or a surface-mount ATmega328.Ĭomparing Technical Features-the first feature to be compared is the microcontroller which is basically the brain of every board. ![]() Its well-known capabilities generally serve as the base features which other boards are compared to. The Arduino Uno is universally known as the ‘stock Arduino’ due to its status as the most popular offering Arduino has offered its teeming users. Most hobbyists generally go for microcontrollers that are cheap and obviously reusable. Cost: the cost of purchasing any of these boards also play a part in deciding which you intend to use.These features consist of items such as flash space, USB, programming interface, etc. Physical Features: this focuses on other features that can be seen by simply observing the physical board.This means we will be taking a look at a system voltage, clock speed, Wi-Fi capabilities, input voltage, Pulse-width modulation (PWM), etc. Technical Features: this criterion focuses on the features that make a board tick.To provide a level playing field, the comparison will be done using a set of criteria that both of our candidates will have to go up against. This is why in this post, two Arduino products-the Mega2560 and Uno R3-will be compared to help you make an educated choice whenever the need arises. The number of products from the Arduino brand means budding developers, as well as professionals when they have to choose among them when in need of a microcontroller.
