A powerful A64 Linux board for Linux based development
The OlinuXino A64 board is a powerful Linux based system running the AllWinner A64 processor. The A64 is a 64 bits ARM processor wiht 4 cores (Cortex A53). All the components on the board have been selected for quality and the board offers a lot of input/output, a physical Gigabit Ethernet port, 1Go of RAM, 4 Go of eMMC memory (to store the OS), an HDMI connector (support full HD video Full HD à 1080p), a WiFi & Bluetooth interface, a LCD screen interface, audio input & output as well as a good documentation. This board offer also many other feature.
The OlinuXino A64 board has a 40 pins GPIO 40 (which is now a kind of standard since Raspberry-Pi) with 2.54mm pin spacing (finaly!!) and a python support for the GPIO.
The A64 processor is so powerful than it is used at Olimex to create the very first open-hardware laptop (the TERES-1).
You can find more information on the manufacturer page.
4Gb eMMC & 1Go RAM
This version of the A64 board bring 4Gb of eMMC memory plus 1 Go of RAM.
The eMMC memory can be used to store the operating system instead of storing it on a microSD card (like the Raspberry-Pi does). It is like the microSD card was integrated to the board.
Why using a eMMC to store the OS?
En embedded system is supposed to be embedded into a car, a train, etc. So the board is vibrating and vibration are not good for mechanical parts on the board. So contact with the microSD in vibrating environment is not suitable as this may result in imperfect contact. Having a eMMC memory soldered on the board takes you away for mechanical issues with the operating system stored on microSD card. The contacts are also free from dusty conditions.
Even better, the eMMC memory is also wired on a "bus" with many signal lines (parallel acces) whereas a SD card is a serial interface (serial acess).
The eMMC offer better performances than NAND memory and eMMC offers a huge increase of performances regading to microSD card.
Installing notes?
Please, follow the Olimex procedure (see tutorial section) to flash the Operating System on the eMMC memory.
Intermediate level required
Using this board requires a minimum of knowledge in the Linux operating system area. The OlinuXIno boards uses a Debian Linux which is also used as base for Raspbian (the Raspberry-Pi's OS).
If you don't have any experience in the Linux area, we strongly recommend to start your experimentation with the Raspberry Pi (it would be an excellent teacher for you).

Software ressources
Link to the Operating System image, instructions, demo software and other, please see the "Software" section in the OlinuXino A64 Olimex's product sheet.
The Python package for A64 under Debian Linux is called pyA64. This package ease the access to the GPIO, I2C and SPI usage. It should already been available on the Debian image. You will find more information and code sample in the library (see the following link):
