1 Overview
1.1 Product Information
The SBC6300X is a single board computer (SBC) designed and built by
Embest. The SBC is based on the Atmel AT91SAM9263 MCU with a 32-
bit ARM instruction set and a complete embedded software environment.
It has a flexible design with a tiny controller board (Mini6300); mounted
directly on an expansion board through two 0.8mm 100pin Free Height
(FH) surface-mount connectors. The CPU board of SBC6300X has the
ARM9 processor and memory on board. The expansion board offers
various hardware interfaces including 8 UARTs, 2 Ethernet ports, USB
Host and Device, CAN, TWI, LCD, Touch Screen, Keyboard, SD card,
Jtag, Audio and etc.
The rich industrial bus interface resources of this sing board computer
makes it ideal for embedded applications requiring wide operating
temperature ranges, and flexible I/O connectivity. It can be used in
many application fields, such as:
Medical Equipment,
Industrial Field Control,
Smart Instrumentation,
Industrial Control Devices,
Monitoring,
Automotive Electronics.

CH0-7 can be connected to your signal directly when the voltage is
bellow +5V
If your signal voltage is above +5V, you need to provide an appropriate
resistance according your project. Then you can measure your signal on
the channel CH0_0-CH7_7.

Appendix 3: ESD Precautions &
Handling Procedures
Please note that the board comes without any case/box and all
components are exposed. Therefore, extra attention must be paid to
ESD (electrostatic discharge) precautions. To effectively prevent
electrostatic damage, please follow the steps below:
Avoid carpets in cool, dry areas. Leave development
kits in their anti-static packaging until ready to be
installed.
Dissipate static electricity before handling any system components
(development kits) by touching a grounded metal object, such as
the system unit unpainted metal chassis.
If possible, use antistatic devices, such as wrist straps and floor
mats.
Always hold an evaluation board by its edges. Avoid touching the
contacts and components on the board.
Take care when connecting or disconnecting cables. A damaged
cable can cause a short in the electrical circuit.
Prevent damage to the connectors by aligning connector pins
before you connect the cable. Misaligned connector pins can cause
damage to system components at power-on.
When disconnecting a cable, always pull on the cable connector or
strain-relief loop, not on the cable itself.
Warning:
This is a class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.
