SECTION 2 1. Setting Up the SBC35-A9G20 Board 1.1. Electrostatic Warning The SBC35-A9G20 board is shipped in protective anti-static packaging. The board must not be subjected to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element. 1.2. Requirements In order to set up the SBC35-A9G20 board, the following items are needed: ● ● the SBC35-A9G20 board itself.
1.4. Powering Up the Board The SBC35-A9G20 requires 5V DC (±5%). DC power is supplied to the board via J3. Coaxial plug center positive standard. 1.5. Getting Started The SBC35-A9G20 board is delivered with a pre-installed U-Boot boot loader and an Embedded Linux operating system. These two components are stored in the NAND Flash. You can update your board by downloading all the available sources and tools on the calao website www.calao-systems.com in order to adapt your system to your needs.
