Chapter 1 About DEBIX

DEBIX is essentially a versatile single board computer, which can be widely used in artificial

intelligence, machine learning, industry 4.0, edge computation, gateway, IoT, security

monitoring etc..

The following are some of the powerful features of DEBIX:

●Powerful Quad Core Arm ® Cortex ® -A53 CPU with a Neural Processing Unit (NPU)

operating at up to 2.3 TOPS.

●The multimedia capabilities include video encode (including h.265) and decode,

3D/2D graphic acceleration, and multiple audio and voice functionalities.

●Real-time control with Cortex-M7. Robust control networks supported by dual CAN

FD and dual Gigabit Ethernet with Time Sensitive Networking (TSN).

●High industrial reliability with DRAM inline ECC.

●Designed for severe environmental conditions and industrial grade temperature

requirements. The wide CPU temperature range of -40°C to 105°C makes it suitable

for extreme operation environments like public transportation and industrial control

etc.

●The size of the board is nearly the same with a credit card, it has multiple extended

ports. This allows DEBIX to give full processor performance while being free from

application restrictions in physical space.

●Support mainstream operating systems including Android, Ubuntu, Yocto and

Windows 10 IoT.

DEBIX has a clear edge in the area of facial and object recognition applications which

combine machine learning and visual processing. Take facial recognition as an example:

DEBIX can simultaneously detect and identify the body frames and facial features of multiple

people. It can also be used in traffic control to identify vehicle types and information of drivers.

Using NPU to perform recognition operations not only increases the recognition speed, but

also sees a noticeable reduction to the burden on the CPU.

DEBIX’s TSN technology makes it essential for Industrial 4.0 applications, as it meets the

needs of industrial enterprises with precision oriented production time control, thus

increasing the interconnection speed of the IoT.

DEBIX Structure Overview

DEBIX's interface features a compact arrangement, the interface components are visible at a

glance. Let’s learn more about DEBIX’s interface through the following Figure 2.

DEBIX Tech Specs

Figure 4

Like any standard computer, DEBIX consists of a range of different computer components.

The most important component is the "brain" of the computer, the system-on-chip/SoC in the

center at the front of the motherboard.

The SoC contains most of the components of the computer, often containing both the central

processing unit (CPU) and the graphics processing unit (GPU). Next to the SoC you will find

another larger chip, the random access memory (RAM).

Figure 5 CPU&GPU Figure 6 RAM

There is a component with a metal cover in the upper left corner of the motherboard, it

contains the wireless communication module which contains the wireless network card and

Bluetooth components.

Figure 7

The eMMC is in the right down direction of WIFI & BT, it integrates a controller in its

enclosure, provides standard interfaces and manage the flash. The PMIC(PCA9450c) is in

the right down corner of the motherboard, it manages the power devices of the host machine.

DEBIX I/O Interfaces

DEBIX has 4 USB3.0 Host A ports, they are all USB3.0 interfaces. The Ethernet port is on

the right side of the USB 3.0, it connects DEBIX to the network through a cable with an RJ45

connector. There are two status indicators below the Ethernet port to show the signal

upstream or downstream status, one is Link, the other is Active:

Figure 8

There is a 3.5mm headphone interface with audio input/output function on the edge of the

board. Next to the headphone interface, there is a Type A HDMI connector for connecting a

display device, TV or projector. On the left side, there is a multifunctional OTG port for

programming, system updating, or USB drive & hard disk connecting etc. Next to the OTG

interface is the USB Type-C power port for DEBIX power supply. We recommend using a

5V/3A power adapter to ensure sufficient power supply.

Figure 9

Next to the OTG port is the CSI connector for camera module connection. There is also a

DSI connector for MIPI touch screen connection.

Figure 10

The 40-pin GPIO connectors on one side of DEBIX are for external hardware connections

such as LEDs, buttons, sensors, and functional modules, among the 40 pins, the 4 pins on

the right side of the 40 pins are called POE (Power Over Ethernet) connectors.
