2 Introduction
Thank you for choosing the MicroSys SBC-LS1088A Single Board Computer
system. This manual should help you to get the best performance and details out
all of its features.
2.1 Safety and Handling Precautions
ALWAYS use the correct type and polarity of the power supply!
DO NOT exceed the rated maximum values for the power
supply! This may result in severe permanent damage to the
unit, as well as possible serious injury.
ALWAYS keep the unit dry, clean and free of foreign objects.
Otherwise, irreparable damage may occur.
Parts of the unit may become hot during operation. Take care
not to touch any parts of the circuitry during operation to avoid
burns, and operate the unit in a well-ventilated location.
Provide an appropriate cooling solution as required.
ALWAYS take care of ESD-safe handling!
Many pins on external connectors are directly connected to the
CPU or other ESD sensitive devices.
Make or break ANY connections ONLY while the unit is
switched OFF.
Otherwise, permanent damage to the unit may occur, which is
not covered by warranty.
There is no separate SHIELD connection.
All the metal sheaths of shielded connectors are connected to
GND.
Also, all mounting holes of the carrier board are connected to
GND.
The module’s mounting holes are not connected to GND
Take this into account when handling and mounting the unit.

additional GPIOs or graphic support if provided by the CPU)
■Added mounting holes for the carrierboard
■Added a fan connector
■Added connector labeling (silkscreen) on the PCB
Some features were changed:
■SerDes 6 and SerDes 7 lanes were swapped in order to achieve a wider
functional coverage within the MPX2 module family
oSerDes 6 is now connected to the SATA connector (ST10)
oSerDes 7 is now connected to the mPCIe / mSATA slot (ST7)
■Improved power input section with filters
■Improved mechanical mounting of the CPU module and mPCIe/ mSATA
cards
■Replaced PCIe x1 edge card connector with second PCIe extension
connector

3 Quick Start Guide
3.1 Prerequisites
Always make sure to handle the SBC-LS1088A unit ESD-safe!
Otherwise, the unit may suffer permanent damage.
However, do not place the unit directly flat on a metal surface,
as this may result in short circuits and damage to the board.
At first time operation unpack the unit and make sure that is clean and free of visible
damage or foreign objects.
3.1.1 Minimum Requirements
To operate the board, you will at least need the following items:
■an adequate power supply, delivering 12V DC (stabilized) / 2A minimum.
■an USB cable (type A –mini B) adapted to connector ST5
■a serial terminal, such as a PC with an USB port running a terminal Software
(e.g. TeraTerm, HyperTerminal, putty, ckermit...), or else a hardware serial
console. Choose the following parameters:
(a) 115200 Bd
(b) 8 Data bits
(c) No parity
(d) 1 Stop Bit
3.1.2 Recommended Items
The following items are not absolutely necessary, but strongly recommended for
practical operation and development purposes:
■Network connection via Port1 to your local network installation
■TFTP server available for downloading within the network (Hint: may run on the
same PC as the serial Terminal)
■SATA HDD/SSD and/or SD card as mass storage and/or boot media
