2 Introduction

Thank you for choosing the MicroSys SBC-LS1028A Single Board Computer system. This manual will provide information for best performance and detailed description of all available 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 wellventilated location. Provide an appropriate cooling solution as required

ALWAYS take ESD precautions when handling the unit. 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. Carrier board mounting holes are not connected to GND. The module’s mounting holes are not connected to GND Take this into account when handling and mounting the unit

3 Quick Start Guide

3.1 Prerequisites

Always make sure to handle the SBC-LS1028A unit in an ESD-safe manner. Otherwise, the unit may suffer permanent damage.

Do not place the unit directly flat on a metal surface, as this may result in short circuits and damage to the board.

First unpack the unit and make sure that it is clean and free of visible damage or foreign objects.

Minimum Requirements

To operate the board, you will at least need the following items:

■ a 12V DC (min 2A) power supply – delivered with the kit

■ a USB cable (type A – mini B) – delivered with the kit

■ a serial terminal, such as a PC with a 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

Recommended Items

The following items are not absolutely necessary, but strongly recommended for practical operation and development purposes:

■ SATA HDD/SSD and/or SD card as mass storage and/or boot media

■ Network connection to your local network

■ TFTP server available for downloading within the network

The TFTP server may run on the same PC as the serial terminal

4.6 Power Supply

Input Supply Rating

The SBC-LS1028A system is run from a single DC power supply with the following ratings:

Maximum Input Voltage Operating Range:

9V - 30V DC

Nominal Input Supply Voltage:

12V DC

Typical Current Consumption (@12V / room temperature / U-Boot prompt):

~0,53A

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.

Input Protection

The board is protected against wrong polarity and over-voltage spikes. Transistor TR3 is installed for polarity protection. It is switched on only if power is

connected with correct polarity (+Vin connected to Pin 1). Otherwise, TR3 will stay off and no internal voltages are generated.

Over-voltage is limited to 33V by a TVS diode. Spikes higher than 33V will be cut off. Please note that applying a permanent power higher than the breakdown voltage will destroy the TVS diode.
