33.0Banana Pi Board  (AllWinner A20 dual-core 1GHz SoC, 1GB DDR3 SDRAM)

It’s an open-source single-board computer. It can run Android 4.4, Ubuntu, Debian, Rasberry Pi Image, as well as the Cubieboard Image. It uses the AllWinner A20 SoC, and has 1GB DDR3 SDRAM. Built with ARM Cortex-A7 Dual-core CPU and Mali400MP2 GPU, and open source software, Banana Pi can serve as a platform to make lots of applications for different purposes. 

Banana Pi has multiple extensible connectors for users to develop their own amazing projects and applications.   Most of common extension accessories Including LCD panel, touch screen, camera module, UART console and GPIO control pins are accessible from Banana Pi on-board connectors and headers. Banana Pi has 26-pins GPIO headers to extend the functions such as I2C, SPI, 5V and 3.3V output…etc.   There are also additional GPIO pins available for extension controls and daughter boards.  For instance, you can use those headers to connect an Arduino board for your projects.  Here could be the start point for your way of exciting applications. CON3 is a DIP-26 headers.  The header pin definitions of CON3 are shown as below. You can connect the headers for I2C, UART, SPI connections.  The 5V and 3.3 V power output are also available here.  Meanwhile, there are several pins free for GPIO pins for your specific usage.

Banana Pi vs. Raspberry Pi

1. The main SoC chip is different.  

2. The physical dimension of  Banana Pi is wider than Raspberry.

3. Banana Pi has more hardware components.

4. The connectors of LCD LVDS interface and Camera interface are different.

In summary, Banana Pi currently has smaller community size, less documentation and it will need to tune OS distribution for Allwinner SoC and its add-on hardware components.
