Arduino Uno Rev3 microcontroller board

The Arduino Uno Rev3 is a microcontroller board based on the ATmega328P. It provides 14 digital input/output pins with 6 PWM outputs and 6 analog inputs. A 16 MHz quartz crystal drives the system clock. The board measures 2.70 by 2.10 inches and connects via USB.

Suitable for learning electronics

This board suits students and makers learning electronics or building sensor and actuator projects. It is the reference model for the Arduino platform and works with the standard IDE. Builders needing integrated wireless connectivity or more memory should consider other options.

ATmega328P with 32KB Flash and 2KB RAM

The microcontroller offers 32KB of Flash memory for program storage and 2KB of RAM for runtime data. This capacity defines the complexity of sketches that can run. Verify that your application fits within these limits before purchasing.

BrandArduino
ModelA000066
FeaturesArduino Uno is a microcontroller board based on the ATmega328P. 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 a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again

商品問答

How do I install the Arduino Uno Rev3 and which step is often missed?

Connect the board to a computer with a USB cable; the driver installs automatically on most systems, but you must select the correct port and the Arduino Uno board type in the IDE before uploading your first sketch.

What maintenance or replacement will the Arduino Uno Rev3 need later?

The ATmega328 microcontroller socketed on the board can be replaced if a pin is damaged; otherwise the board has no moving parts or consumable components that require scheduled servicing.

What limit appears first when the Arduino Uno Rev3 runs continuously?

The 32 KB flash memory and 2 KB RAM on the ATmega328 constrain program size and variable space, so large sketches or heavy data buffering hit that ceiling before thermal or power limits.
