INTRODUCTION

The SMARC mainboard MB-SMARC-3 is a carrier board for SMARC modules with a pinout based on the SMARC 2.1 specification.

It can be used for panel PCs, embedded computers or as evaluation platform for SMARC modules.

In combination with a standard SMARC module it forms a very compact hardware kit that can be used for a freely scalable

embedded PC platform thanks to its modular design. Because of this – with uniform interfaces and dimensions – the PC system

can be easily adapted to suit the requirements of the application. The many extension options and storage media, which can be

added, offer a high level of flexibility and allow functionalities and performance to be extended easily, quickly and inexpensively.

Typical usage is in embedded server applications, PC systems, automation, visualisation and monitoring and all applications that

place high demands on quality, durability and long-term availability.

3.2.1 Supply Voltage Characteristics

The MB-SMARC-3 requires an input voltage of 12 V DC ±5 %.

The input voltages shall rise from 10 % of nominal to 90 % of nominal within 0.1 ms to 20 ms.

(0.1 ms ≤ Rise Time ≤ 20 ms).

There must be a smooth and continuous increase of each DC output voltage from 10 % to 90 % of its final set point within

the regulation range.

3.2.2 Power Consumption Specification

The power consumption of the system significantly depends on the connected devices (SMARC module, Mass storage devices,

USB devices, display backlight etc.).

The power consumption of the MB-SMARC-3 itself is approximately 2 W (SMARC module supplied externally;

UEFI-shell active; no keyboard, no mouse, no mass storage device etc. connected).

The maximum input current of the MB-SMARC-3 is limited to 5 A by a fuse. The load caused by devices connected to the carrier

board should not exceed 50 W.

Note: Power requirement

The power supply for the MB-SMARC-3 must be configured with enough reserve.

It should be calculated with the maximum power consumption of all connected components.

3.6.8 LVDS

The MB-SMARC-3 provides an LVDS interface for direct connection of suitable displays. This functionality is only available when

the connected SMARC module provides LVDS and the multiplexer on the mainboard is switched to LVDS interface (DIP switch S2

is “OFF”).

Please contact TQ-Support for further information about eDP or LVDS support.

There is also a connector on the carrier board to power the display backlight (for further information see next page).

The MB-SMARC-3 has an on-board EDID EEPROM to store display specific timing information. This EEPROM can be programmed

with an external I2C programmer. If the programmer supports 3.3 V output voltage, the MB-SMARC-3 can be programmed

without any additional power supply. In this case no SMARC module should be connected to the carrier board.
