4.2.2 mikroBUS™ Socket
ATmega4809 Xplained Pro has one mikroBUS socket that can be used with MikroElektronika click modules. The table below shows the signals connected to the mikroBUS socket.
| Function | ATmega4809 Pin | mikroBUS™ | ATmega4809 Pin | Function | |
|---|---|---|---|---|---|
| ADC0 AIN6 | PD6 | AN | PWM | PF4 | TCB0 WO (TCA0 WO4) |
| GPIO | PD0 | RST | INT | PE2 | GPIO |
| GPIO | PF2 | CS | RX | PB1 | USART3 RxD |
| SPI0 SCK | PA6 | SCK | TX | PB0 | USART3 TxD |
| SPI0 MISO | PA5 | MISO | SCL | PC3 | TWI0 SCL |
| SPI0 MOSI | PA4 | MOSI | SDA | PC2 | TWI0 SDA |
| — | — | 3.3V | 5.0V | — | — |

Info:
All signals on the mikroBUS socket are shared with Xplained Pro extension header EXT3.
Make sure that the connected mikroBUS add-on board and Xplained Pro extension does not use the same signals if both connectors are used at the same time.
Attention: 3.3V and 5.0V are
connected directly to the mikroBUS socket. It is important to make sure the ATmega4809 operates at the same voltage as the
connected mikroBUS socket. The operating voltage for the ATmega4809 is selected with the power selection header J105.
