- SDMMC: One standard 4-bit SD card interface
- USB: two stacked Type-A connectors with power switches, one micro-B
       USB device
- CAN: 2 interfaces (Microchip MCP2542)
- Ethernet: one 10/100Mbps
- WiFi/BT: one optional WiFi/Bluetooth interface
- Audio: one ClassD port
- Display: one 24-bit LCD interface
- Camera: one 12-bit image sensor interface
- IO: one IO expander (Microchip MCP23008)
- Debug ports: one J-Link-OB + CDC, one JTAG interface
- Leds: one RGB LED
- Buttons: 4 push button switches
- Expansion: one PIO connector, one mikrobus connector
- Power management: two power regulators, two power consumption measurement
                    devices
