How to use
Install a compatible operating system image to a microSD card and insert it into the board, connect power via the USB-C input and attach a display, keyboard and mouse as needed. Configure wireless settings or connect an Ethernet cable to access the network. Use the GPIO header for connecting sensors, actuators or HATs, and attach external storage or USB peripherals to expand functionality. For first-time setup, follow official system setup instructions and verify required power supply rating and cooling if running processor-intensive tasks.
Usage recommendations
For reliable operation, use a stable 5V USB-C power supply with adequate current and a quality microSD card class suited for frequent read/write operations. Consider passive or active cooling when running sustained workloads and keep the board in a ventilated enclosure. Regularly back up microSD storage and apply software updates to maintain security and compatibility.
