Get Arduino Nano Number Of Digital Pins
Pictures. I suspect the digital pin count includes the tx and rx and analog pins, which are also usable as digital pins (except for a6 and a7 which are analog only, so the correct number of pins would be 20, not 22). The pins work with 5v voltage as.
Arduino Nano Architecture And Arduino Gui Introduction To The Internet Of Things Iot from carpentries-incubator.github.io
The arduino nano is the smallest microcontroller in the arduino family and has therefore the lowest number of pins and connections. The atmega328 provide uart ttl (5v) serial communication, which is available on digital pins 0 (rx) and 1 (tx). Both arduino uno and arduino nano come with same functionality with little difference in terms of pcb layout, size and form factor.
While the title of this document refers to digital pins, it is important to note that vast majority of arduino (atmega) analog pins, may be configured, and used.
I suspect the digital pin count includes the tx and rx and analog pins, which are also usable as digital pins (except for a6 and a7 which are analog only, so the correct number of pins would be 20, not 22). These secondary pins are mostly communications pins such as i2c and spi. Both arduino uno and arduino nano come with same functionality with little difference in terms of pcb layout, size and form factor. Arduino nano has similar functionalities as arduino duemilanove but with a different package.
