3 Getting started
3.1 Prerequisites
Before you power up your DB4 for the first time you will need the following:
DB4 board.
A 96Boards compliant power supply (sold separately by Geniatech).
A HDMI or DVI LCD Monitor that supports a resolution of 1080P/30Hz.
HDMI-HDMI cable or HDMI-DVI cable to connect the board to the Monitor.
A computer keyboard with USB interface
A computer mouse with USB interface.
3.2 Starting the board for the first time
To start the board, follow these simple steps:
step 1. Connect the HDMI cable to the DB4 HDMI connector (marked J6) and to the LCD Monitor.
step 2. Connect the keyboard to the boards USB connector marked J3 and the mouse to the USB connector
marked J2. (It doesn’t matter which order you connect them in.
step 3.
Ensure that the boot switches S6 are set to ‘0000’, all in Off position.
step 4. Connect the power supply to power connector J1.
Once you plug the power supply into a power outlet the board will start the booting process, and you should see Android
boot up.
You can also connect via an external USB Hub.)
Please note that the first boot takes several minutes due to Androids initialization. Subsequent boot times should be faster.

4 DB4 Overview
4.1 System Block diagram
4.2 Processor
The Snapdragon 410 APQ8016 is a quad 64-bit ARM Cortex-A53 MPcore Harvard Superscalar core, supports both LP-DDR2
/ LP-DDR3 SDRAM interface, Hexagon QDSP6, 13.5 MP camera input support, Adreno 306 GPU, 1080p video
encode/decode, Bluetooth 4.1, OpenGL ES 3.0, DirectX, OpenCL, Renderscript Compute, FlexRender support.
4.3 Memory
The DB4 uses a single embedded Multi Chip Package (eMCP) dual function LPDDR3/eMMC memory solution. The installed chip
provides 16Gbyte of solid state storage and 2Gbyte of LPDDR3.
The LPDDR3 is a 32bit width bus implementation interfacing directly to the APQ8016 build-in LPDDR controller.
The maximum DDR clock is 533Mhz
The eMMC is an 8bit implementation interfacing with APQ8016 SDC1 interface supporting eMMC 4.5
specifications.
4.4 MicroSDHC
The 96Boards specification calls for a microSDHC socket to be present on the board.
