4412 Core Board Introduction

Two package formats: The Exynos4412 is available in two packages, and the POP -encapsulated chip contains 1GB of memory, so there is no need for an out -of-band DDR ,

Can greatly save PCB area, power control is also better, more for handheld devices; the SCP package has the advantage of being more flexible in memory expansion and easier to control the production process.

4412POP Package

Length width:5CM * 6CM, height 1.5MM, 4 pin (*+);

Onboard 1GB memory, power management;

When assembling with the baseplate, note the "anti-stick Arrow".

4412SCP Package

Length width:6CM * 7CM, height 1.5MM, 4 pin (*+);

SCP onboard 1G or 2G memory, power management;

When assembling with the baseplate, note the "anti-stick Arrow".

4412 Development Board Backplane:

iTOP-4412 All-in- all board as shown:

OTG Interface :

The OTG interface is used to burn the image and can also be used as a debug port for Android app apps . On the Android system

The following can be used to upload files and install the app(it works well without a network).

USB Interface :

the USB interface can be used to connect the mouse and keyboard. can also be used to connect PL2303 to extend the serial port, but need

The driver to load the PL2303 .

WIFI/BT Module

Users should pay attention to distinguish,wifi/bt module is GT-900, the chip in the module is s500m.

TF and SD Card Interface

All-in-one version can use TF card or SD Card, two options, for burning the system or storing data, burning system in the third

Chapter has a detailed introduction, the use of stored data similar to the TF card in the phone .

Gyroscope Gyroscope, accelerometer Accelerometer module: This module is a gyroscope and accelerometer two in one.

3G module: WCDMA 3G module available

Key key: Press to provide sleep/ Wake, Volume +, Volume -, back,HOME function.

Graphics resources and Interfaces: The iTOP-4412 has a rich video output interface, including HDMI and LVDSas shown.

MIPI Interface : HD MIPI interface

GPS module: using GNS7560.

Camera Camera+avin expansion Port : support camera Camera+avin expansion Port

Real-time Clock RTC: in Android4.0.3 , after installing the CR1220 Lithium battery, the clock can also work after a full power outage.

Sound card resources and interface: The sound card has headphones and headset interface, as well as The speaker package for the PIN2 loudspeaker expansion Port three.

Thin-code switch and corresponding function: The iTOP-4412 Development Board can control the starting mode and the output of the video card through the thin code switch. For example, XOM2, XOM3,XOM5 for controlling the 4412 Start-up mode, Ap_sleep , XEINT6 used to control the graphics output.

Ethernet: Ethernet Enabled

Can modules:can is extended via the exnoys4412 SPI bus.

RS485 module:RS485 is exnoys4412 through the serial port extension.
