Arduino Nano Every
This board is based on the ATMega4809 microcontroller.
Clock: 20MHz
Flash: 48KB
SRAM: 6KB
EEPROM: 256byte
An ATSAMD11D14A Processor takes care of the USB to SERIAL communication and it is connected to the following pins of the ATMega4809 microcontroller.
ATMega4809 Pin -- ATMega4809 Acronym -- SAMD11 Pin -- SAMD11 Acronym -- Description
9 -- PB05 -- 15 -- PA22 -- SAMD11 TX -> ATMega4809 RX
8 -- PB04 -- 16 -- PA23ATMega4809 TX -> SAMD11 RX
41 -- UPDI -- 12 -- PA15 -- UPDI RX
