ITEAD A10 CORE is a minimum system module based on design of A10 chip. With ARM Cortex A8 core, it supports maximum frequency up to 1GHz. The module is equipped with 1G DDR3 memory and 4G FLASH. The digital circuit section and the overall power design of SDRAM on the module has been completed, so it can work directly after powering up with a stable 5V supply.

ITEAD A10 CORE is a minimum system module based on design of A10 chip. With ARM Cortex A8 core, it supports maximum frequency up to 1GHz. The module is equipped with 1G DDR3 memory and 4G FLASH. The digital circuit section and the overall power design of SDRAM on the module has been completed, so it can work directly after powering up with a stable 5V supply.

To use ITEAD A10 CORE for project development, design of complex multi-layer high-speed circuit is not required, as you only need to provide it with a stable 5V power supply and connect the pins on the module to the corresponding socket (such as HDMI, Micro-SD card, USB, etc.), or to the relevant circuit bus (such as I / O ports, UART, SPI, etc.). With design of such functional board, the difficulty will be decreased compared to directly using chips with SDRAM, FLASH, power circuit and functional circuit for the layout and the project development cycle will also be greatly reduced.

Note 1: There are two versions of NAND FLASH capacity: 0G and 4G.

Note 2: Working current (low load) refers to the working current when no other operations are done (CPU occupancy rate of about 2%) after entering ITEAD OS instead of the minimum working current; SATA hard drive is a big power consumer, working current will reach up to 550mA when connecting2.5-inch SATA hard drive in the low load condition. Note 3: Working current (high load) refers to the working current when CPU is doing super pi operation (CPU occupancy rate of about 98%) after entering ITEAD OS instead of the maximum working current.
