OK4418 is an Embedded Computer (Single Board Computer) based on the 1.4GHz Samsung S5P4418 (ARM Cortex-A9) microcontroller. OK4418 embodies abundant of built-in resources and powerful video processing capacity, which make the OK4418 reliable for the development of higher-end products. Together with the OK4418 we provide BSPs (Board Support Packages) for Embedded Linux and Android including basic drivers for all the components on the board and illustrating programs, which we believe can help the users in understanding the ARM architecture and shortening their development circle. Here are some dos and don’ts for using the OK4418: 1.
After opening the OK4418 package, please check and make sure that the following components are all enclosed: 1 × OK4418 board 1 × serial port cable 1 × USB cable 1 × 5V power supply 1 × DVD
2.
DO NOT plug/ unplug the core board when power is on.
3.
The core board connector should not be touched by finger or oil.
4.
When using the Development Board for the first time, please do read and follow the user manual to prevent unnecessary troubles and damages.
5.
Every time before powering on the Development Board, please touch anyone of the metallic interface with your fingers to unload the Electrostatic. Do not touch the chips with your fingers!
6.
Before physically operating the Development Board, please switch the power off. Hot plugging is not supported except on the USB and Ethernet interfaces.
7.
We provide for the OK4418 12 weeks’ guarantee (in the precondition of non-artificial damage) and 24 weeks’ technical support. Editor: Witech Co. Ltd. Tel: 86-871-65899845 Fax: 86-871-65899845 Email:

1. Brief Introduction The Witech OK4418 is a development platform based on the Samsung S5P4418 ARM Cortex-A9 quad-core 1.4Ghz microcontroller. Carrying 1GB DDR3 RAM, 8GB eMMC ROM, on-board Gigabit Ethernet, DVP&MIPI camera interface, LVDS& DHMI& LVD& MIPI display output, 5 x UART, 2 x USB Host, 1 x USB OTG, supporting Bluetooth & WIFI, the OK4418 makes itself a powerful and suitable device for developing and implementing kinds of industrial products.
The OK4418 Development Board is split into two parts, a core board and a carrier board. The core board is actually the central controlling module of the Development Board, which embodies the S5P4418 CPU, DDR3 RAM, eMMC and power management unit. Measuring only 45 x 60mm, the core board can be connected to the 130 x 190mm carrier board via four 80pin anti-oxidation connectors; once programmed, it can be also detached from the carrier board and used as individual COM (Computer On Module) and inserted like a "big chip" into test beds, prototypes, and production units for OEM deployment. The OK4418 Development Board is designed in conformity with CE standard with full consideration to high speed signal competence, EM compatibility, and static protection and etc., to ensure stable performance under various environments. Together with the OK4418 we provide BSP (Board Support Packages) for Android 5.1.1 and Embedded Linux-3.4.39 and QT4.8.6, which provide drivers for all the bottom interfaces and devices and utility applications.

2. S5P4418 S5P4418 is a system-on-a-chip (SoC) based on the 32-bit ARMv7-A architecture for tablets and cell-phones. S5P4418 uses the ARM Cortex-A9 in a quad core configuration, the latter provides a 50% overall performance boost over the earlier Cortex-A8 core. The SoC memory controller supports a maximum memory bandwidth of 6.4GB/s for heavy traffic operations such as 1080p video encoding and decoding, 3D graphics display and high resolution image signal processing with a Full HD display. The application processor supports dynamic virtual address mapping, which helps software engineers to fully utilize the memory resources with ease. The S5P4418 features the Mali400MP graphics processing unit which supports OpenGL ES 1.1 and 2.0. The native dual display, in particular, supports Full HD resolution of a main LCD display and 1080p 60 frame HDTV display throughout HDMI, simultaneously. Specifications:
