4.4 Peripherals
4.4.1 ATmega4808
Microchip ATmega4808 is a microcontroller featuring the AVR
®
processor with hardware multiplier - running at up to
20 MHz and with up to 48 KB Flash, 6 KB SRAM and 256 bytes of EEPROM in 28- and 32-pin packages. The series
uses the latest Core Independent Peripherals (CIPs) with low-power features, including event system, intelligent
analog and advanced peripherals.
4.4.2 mikroBUS
™
Socket
AVR-IoT Wx features a mikroBUS socket for expanding the functionality of the development board using
MikroElektronika Click Boards and other mikroBUS add-on boards. The socket is populated with two 1x8 2.54 mm
pitch female headers and is ready to mount add-on boards.
