4. Setup Guide
Follow these steps to set up your Radxa Rock 5A:
- Prepare Storage:
Install an operating system (OS) onto a microSD card or an eMMC module. You will need a separate computer to flash the OS image onto your chosen storage medium. Refer to the official Radxa documentation for supported operating systems and flashing instructions.
- Connect Peripherals:
- Connect a monitor to one of the HDMI ports.
- Connect a USB keyboard and mouse to the USB 2.0 or USB 3.0 ports.
- (Optional) Connect an Ethernet cable to the Gigabit Ethernet port for network access. If using PoE, ensure your network switch supports it.
- (Optional) Connect any other desired peripherals such as a fan to the fan header, or an M.2 E Key module.
- Insert Storage:
Insert the prepared microSD card into the TF Card Slot or connect the eMMC module to its dedicated connector.
- Apply Power:
Connect a compatible USB Type-C power adapter to the USB Type-C Power port. The board should power on automatically, or you may need to press the Power Button.
- Initial Boot:
Allow the system to boot up. The first boot may take longer as the OS initializes. Follow any on-screen prompts to complete the OS setup.
