SECTION 2
1. Setting Up the SBC35-A9260 Board
1.1. Electrostatic Warning
The SBC35-A9260 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-A9260 board, the following items are needed:
● the SBC35-A9260 board itself.
● AC/DC power adapter (5V at 2A), 2.1 mm by 5.5 mm
1.3. Layout
Datasheet USG-00001-B01 5/28
1.4. Powering Up the Board
The SBC35-A9260 requires 5V DC (±5%). DC power is supplied to the board via J3.
Coaxial plug center positive standard.
1.5. Getting Started
The SBC35-A9260 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.
