An Arduino core for ATmega4809, ATmega4808, ATmega3209, ATmega3208, ATmega1609, ATmega1608, ATmega809 and ATmega808. This megaAVR-0 chip family offers lots of features and peripherals at an incredible price point. Its largest variant, the ATmega4809 can be found in products like the Arduino Uno WiFi Rev2 and the Arduino Nano Every. Some of their key features include multiple serial ports, SPI and i2c interfaces, built-in programmable logic, up to 16 analog input pins, and an analog comparator with a built-in programmable voltage reference and hysteresis. Compared to older AVR families they also have more advanced and accurate internal oscillators which can provide base frequencies of 16 and 20 MHz. These can again be divided down internally to reduce the processor speed and power consumption. This means in most applications an external clock isn't necessary anymore.
