I will discuss about the pins of Arduino UNO in the Arduino UNO Pinout Section. There is also a 2.1 mm DC jack to provide external power supply.Īpart from that, the layout of Arduino UNO is very much self-explanatory. Layout of Arduino UNO BoardĪs you can notice, there is a Type-B USB connector on the left short edge of the board, which is used for powering on the board as well as programming the Microcontroller. All the components are placed on the top side of the PCB. The following image shows the layout of a typical Arduino UNO board. Other than that, rest is identical in both the boards. Arduino UNO comes in two variants: one consists of a 28-pin DIP Microcontroller while the other consists of 32 lead Quad Flat Package Microcontroller.
Arduino UNO in DIP and SMD PackagesĪrduino UNO is based on ATmega328P Microcontroller, an 8-bit AVR Architecture based MCU from ATMEL. There are other boards like the Arduino Nano and the Arduino Mega, but UNO has been the go-to board for quick prototyping, Arduino Projects and DIY Projects. Perhaps the most popular board in the Arduino line-up is the Arduino UNO. What Communication Interfaces are available on Arduino UNO?.What are the Input and Output Pins of Arduino UNO?.What are Different Memories of Arduino UNO?.Technical Specifications of Arduino UNO.
