The arduino uno is one kind of microcontroller board based on atmega328, and uno is an italian term which means one arduino uno is named for marking the upcoming release of microcontroller board namely arduino uno board 10this board includes digital i/o pins-14, a power jack, analog i/ps-6, ceramic resonator-a16 mhz, a usb connection, an rst button, and an icsp header. Arduino uno atmega328 pin diagram. When converting your design from an arduino uno to a raw atmega328 chip it is helpful to be able to relate the pinouts on the atmega328 to the connections on an arduino uno the following pinout diagram has been relabeled to show the arduino uno equivalent functions:.
arduino uno atmega328 pin diagram
Arduino uno is a microcontroller board based on the atmega328p ( datasheet ) it has 14 digital input/output pins (of which 6 can be used as pwm outputs), 6 analog inputs, a 16 mhz quartz crystal, a usb connection, a power jack, an icsp header and a reset button it contains everything needed to support the microcontroller, simply connect it to. We all know that, atmega328 ic is used in arduino uno board. this ic is the brain of the arduino board. its pin diagram is given above. crystal oscillator: a 16mhz external crystal is connected between pin 9 and pin 10 of the atmega328. this crystal is used to give clock to the microcontroller to execute the tasks faster.. Arduino atmega328 pinout. 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.
