But it’s not easy to program a Microcontroller directly due to the absence of a USB port, GPIO header, etc., and hence it is not recommended to beginners.ĭevelopment board: A development board makes it easy to connect the external peripherals to the Microcontroller. That’s why a Microcontroller can execute commands by itself. Microcontroller: A microcontroller is made up of a Microprocessor and other units required to perform certain functions like Memory units, Inputs/Outputs, ADCs, etc. It needs external components and devices like RAM, ROM, Registers, I/O, etc, to send or store the data. But it’s important to note that a microprocessor cannot execute commands by itself. And is responsible for executing the commands that are given to the system (like Arduino UNO).
It performs all the numeric and logic calculations. Microprocessor: It is the brain of any embedded system. Microprocessor VS Microcontroller VS Development board You can say, atmega328p is the brain of the Arduino UNO development board. It is actually a development board that uses a microcontroller called Atmega328p to perform various functions. Is Arduino a Microcontroller or Microprocessor?Īrduino UNO is neither a microprocessor nor a microcontroller. Microcontrollerģ2 KB (ATmega328P) of which 0.5 KB used by the bootloader
Given below is the brief info about the specs of the latest Arduino UNO Rev3 board like the Microcontroller used, number of digital/analog pins, memory, voltage, and current ratings, etc.
