Arduino-UNO-PCB-Design This repository contains full PCB design of Arduino UNO. This design was done completely from scrath, starting with selecting components from digikey, creating schematic symbols ...

Pin 2 on the Arduino schematic is really GPIO2 on the NINA, therefore it should not be labeled GPIO34. This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin ...

The Arduino UNO has 14 digital I/O pins and 6 Analog inputs. The digital I/O pins are 5V logic level and you can also use the Analog pins as digital I/O too. Arduino UNO supports 6 channel 10 bit ADC ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

DC Current per I/O pin – 8 mA; Arduino UNO R4 WiFi only Qwiic I2C connector for expansion modules. 3-pin header with an “OFF” pin to turn off the board and a “VRTC” pin to keep the internal Real-Time ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. ... the UNO R4 WiFi introduces a built-in 12×8 LED matrix, a Qwiic connector, and a VRTC and OFF pin. ...
