Communication Rock Pi 4 Model A
Rock Pi has basic communication interfaces that can be found in PC-class office computers. The user has it at his disposal:
- Two USB 2.0 connectors,under which you can connect e.g. a mouse, a keyboard, a WiFi card or a flash drive. If it turns out that there are too few sockets, you can increase their number by usingan external USB HUB.
- Gigabit Ethernet socket, which means that you can connect directly to your LAN. The minicomputer also supports PoE power.
- GPIO x 40 pin- general purpose outputs/inputs that can be used for LEDs, buttons, motor controllers. Among them there are pins supporting interfaces: I2C, SPI and UART.
- MicroSD slot- slot for a microSD memory card, on which the operating system can be installed.
- CSI connector- socket for connecting the camera. Works with officialRaspberry Picameras.
- DSIconnector - socket for connecting the display. Rock Pi cooperates with the officialRaspberry Pi screen.
Rock PihasHDMIconnector, throughwhich you can transmit both video and audio in 4K quality.
