描述 Description

Arduino? Nano Every is a miniature sized module containing an ATMega4809 AVR processor and an ATSAMD11D14A Arm? Cortex?-

M0+ processor to act as a bridge between USB and the main AVR processor. The module can either be mounted as a DIP component

(when mounting pin headers), or as a SMT component, directly soldering it via the castellated pads.
