Chapter 2 Introduction of Hardware System
This chapter will introduce the structure, expansion and peripheral interfaces of MaaXBoard hardware
system in details.
2.1 MaaXBoard Hardware Installation and Start up
2.1.1 Installation
Before powering up the MaaXBoard, you need to connect all necessary peripheral devices, then power
on the board.
2.1.2 Booting Configuration
According to the manufactured configuration, MaaXBoard supports two boot modes: boot from Micro SD
card or boot from eMMC. By default, the AES-MC-SBC-IMX8M-G only supports SD Card boot. Both the
SD Card foot print and eMMC footprint are on top of each other so only one or the other can be populated
at the same time. If interested in eMMC configuration, Avnet does offer BOM customization services to
populated the eMMC footprint over the SD Card footprint. Contact [e-mail] for details.
These two boot modes are mutually exclusive. If users choose to boot from Micro SD card, they should
burn the latest image to the card on PC, then install the card to the board, refer to the software user
manual. If users choose to boot from eMMC, just power on the board.
Note: If the eMMC firmware is destroyed by accident, users could update the eMMC image in USB
Download mode. Please operate carefully and follow the steps in software user manual strictly to avoid
damaging the product.

2.2 Details of Interfaces
This section will introduce the constructions, principles, interface definitions and considerations of use of
MaaXBoard peripherals in detail, so that users may have a deep understanding of the hardware circuitry
of the board.
2.2.1 POWER IN
MaaXBoard use a USB Type C interface as the +5V power in. Note that the USB Type C interface only
provides power supply function, do not support data communication.
The Power adapter should support 3A or above current output.

2.2.2 Button
There are 3 buttons on the MaaXBoard, S2 as the system power button for the board, S3 and S4 as user
button.

2.2.3 HDMI
Powerful video display is an important feature of MaaXBoard. The HDMI 2.0 interface support up to 4096
x 2160 at 60Hz display output.
J9 is the interface for connecting an HDMI display device on the MaaXBoard, which is a standard HDMI
19Pin connector. Its specification and dimension as follows:
