Arduino NANO Every

This small, robust and powerful board has the same classic Nano footprint
loved worldwide.
It can be programmed with the easy to use Arduino IDE available offline
and online. Get started in minutes with thousands of sketches available in
open-source or write your own: it is the perfect choice for your everyday
projects. Based on the ATMega4809 AVR processor, the Arduino Nano Every is
flexible to the requirements of your design. It can be used in a breadboard
when mounting pin headers, or as a SMT directly soldered on a PCB
thanks to its castellated pads. An SAMD11 ARM Cortex M0+ processor
acts as a high performance USB to serial converter that can be reprogrammed by skilled users to expand further the applications of this
board.
