Arduino uno atmega328 pin diagram. Weve created a well explained diagram based pin out representation of arduino nano. Arduino nano pin diagram click the image to enlarge it arduino nano pin configuration. Arduino leonardo v2 pinout diagram. They are all titled something like the unofficial arduino pinout diagram the definitive arduino pinout diagram etc.
Arduino uno is based on the atmega328 by atmel. Arduino mega v1 pinout diagram. Last year i found some awesome arduino pinout diagrams with full colour on the arduino forums. In this guide learn about arduino nano pin outs and diagrams.
Software arduino ide integrated development environment is required to program the arduino uno board. Atmega328 is the controller that is used in arduino uno. The arduino mini is based upon a smaller physical ic package that includes two extra adc pins which are not available in the dip package arduino implementations. For arduino nano use tqfp pin configuration thin plastic quad flat package while arduino uno uses pdip pin configuration plastic in line packages.
The arduino uno pinout consists of 14 digital pins 6 analog inputs a power jack usb connection and icsp header. Note that this chart is for the dip package chip. For those of you who are using an atmega328 with the arduino bootloader code on your own circuit board here is the pinout details which shows the chip pin numbers and the associated arduino pins. Arduino nano and arduino uno both use atmega328 microcontroller series but the pin configuration model of atmega328 chip used by nano and uno is different.
Input voltage to arduino when using an external power source 6 12v. Arduino uno v3 pinout diagram. Vin 33v 5v gnd. When atmega328 chip is used in place of arduino uno or vice versa the image below shows the pin mapping between the two.
The arduino uno pinout consists of 14 digital pins 6 analog inputs a power jack usb connection and icsp header.
