ITeaduino Plus A20
Iteaduino Plus is a Cost - effective DIY ARM platfrom. If you plan to assemble a small computer, you can try using this small ARM platform. It supports Ubuntu and other Linux distributions,you could use it like an ordinary computer. At the same time, the platform also have many extension interfaces, so you can make it as a brain for all your DIY project.
Iteaduino Plus is made up of Core and Baseboard. Core is the smallest system based on ARM, and it forms a highly extendable Mini PC together with Baseboard. Core and Baseboard are detachable. A relatively high-speed circuit is integrated in Core, which is quite difficult to design, and users can develop Baseboard on their own according to their needs.

- GPU Mali 400 MP
- DDR3 RAM 1Gbit
- 4G NAND FLASH
- Split CORE and Baseboard design
- Break out sufficient GPIO’s
- Compatible with RPI 26pin interface
- Support Grove Electronic brick
- Support Foca directly for serial debug

Note:
- As power supply from USB port of PC can only support the system working properly under low load, an external AC ~ DC power supply is recommended to ensure system working normally under high load.
- When A20 Core works under large load, voltage loss on USB power cable should be considered, as there might be abnormities such as program running away due to insufficient input voltage. To ensure a good power supply, we customized a batch of high-quality USB power cable, and the internal resistance is controlled to about 400 ohm. We recommend using the USB power cable supplied by ITEAD to ensure sufficient supply voltage, do not use power cables of poor quality.
