The Curiosity Nano uses an ATmega4809 but has a different pinout than the Uno Wifi Rev2. The recommended pinout for this board is 48 pin standard. The on-board LED is connected t pin PF5 (digital pin 39). Note that UART3 is connected to the nEDBG chip (often referred to as the deb...
This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux ...

Also, the Arduino board can operate on an external power supply of 6V to 20V. However, the recommended power supply range is 7V to 12V. Besides, it displays the CO2 data from the CO2 sensor on the serial port simultaneously, which is not possible for Arduino Uno with higher baud rates ...

On the Arduino Uno, port D contains pins 0 to 7, port B pins 8 to 13, and port C A0 to A5. There are 3 registers to control the I/O (where x is the port letter): DDRx: Data Direction Register: this sets whether the pins of the port are inputs(1) or outputs (0). (pin...
I2C is a complicated transmission protocol, but it's very useful. All Arduinos implement it, with a few differences in pin mappings: Board I2C pins Uno, Pro Mini A4 (SDA), A5 (SCL) Mega, Due 20 (SDA), 21 (SCL) Leonardo, Yun 2 (SDA), 3 (SCL) ...
