CHAPTER 2: SETTING UP THE OLINUXINO BOARD
2. Introduction to the chapter
This section helps you set up the OLinuXino development board for the first time. Please consider
first the electrostatic warning to avoid damaging the board, then discover the hardware and software
required to operate the board.

detailed.
2.1 Electrostatic warning
OLinuXino is shipped in a protective anti-static package. The board must not be exposed 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.

2.2 Requirements
In order to set up the A20-OLinuXino-MICRO optimally one or more additional items may be used.
They might be generally placed in three categories:
They might be generally placed in three categories:
Required - items that are needed in order to achieve minimum functionality;
Recommended – items that is good to have in order to be able to interact with the most important
of the features of the board;
Additional – items that provide access to additional features or expand the features of the board.
Recommended – items that is good to have in order to be able to interact with the most important
of the features of the board;
Additional – items that provide access to additional features or expand the features of the board.
Required items:
- USB type A to USB mini cable – to connect to a personal computer; used for powering the board
and uploading new Android image to the NAND memory (if your board has 4GB NAND)
- Input device – either a mouse/keyboard or touchscreen LCD
- Output device – either HDMI cable + native HDMI monitor/screen/projector; or USB-SERIAL-
CABLE-F + personal computer (for Linux and/or Android debugging); or OLIMEX LCD (TS)
display + 40-pin CABLE-IDC40-15cm; or A20-VGA-CABLE + VGA monitor/screen/projector
- SD card with compatible image – if you have the board version with NO additional NAND
memory you will need it to use one of the images available.

Recommended items:
- External USB hub – to split the USB_HOST mounted on the board; you need that to connect more
USB devices
- External power supply unit – 6-16V DC, 5W required (10V @ 0.5A) – for optimal power
- USB-SERIAL-CABLE-F – for Android/Linux debugging on UART0
- CABLE-IDC40-15cm – cable used for LCD_CON ↔ Olimex LCD display
- Adapter cable for the 6-pin VGA connector to standard VGA 15-pin connector
