I myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout. That is why I have written this ...

The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...

Note: Some pins are not connected on a standard Arduino Uno R3 but still listed so you can use them if you had a custom board. It might also be possible that your ISP header of the 16u2 is flipped 180 ...

Arduino Uno pinout There are two kinds of pins: GPIO and power pins. GPIO pins let you process inputs and outputs. By default, all Arduino pins are inputs. On the other hand, power pins are meant for ...

The Board Overview Now, if we look at the Arduino Uno R4 WiFi development board, we can see that it comes with many hardware upgrades over its predecessor. Here is a part marking image of the Arduino ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

RA4M1 microcontroller block diagram The new Arduino UNO R4 board also adds a CAN bus and a 12-bit analog DAC. Two versions of the new 32-bit Arduino UNO board will be offered: UNO R4 WiFi and UNO R4 ...
