Based on the ATMega4808 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 re-programmed by skilled users to expand further the applications of this board.
If you bought an Arduino Nano Every Klon (Thinary AVR Boards), most probably; a. Your usb chip is CH340, not ATSAMD11D14A. Firstly you should install driver for this chip,b. Your microcontroller is ATMega4808, not ATMega4809. You should add your drivers to Arduino IDE according to the link. https://github.com/Thinary/ThinaryArduinoNot: You may check your chips by a magnifying glass or high-resolution mobile phone camera.
