Chapter 2 Introduction of Hardware System
This chapter will introduce the structure, expansion and peripheral interfaces of MaaXBoard Mini
hardware system in details.
2.1 MaaXBoard Mini Hardware Installation and Start up
2.1.1 Installation
Before power up MaaXBoard Mini, you need to connect all necessary peripheral devices, then power on
the board.
2.1.2 Booting Configuration
According to the manufactured configuration, MaaXBoard Mini supports two boot mode: boot from Micro
SD card or boot from eMMC. These two boot mode is mutual exclusion. 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 Miniperipherals in detail, so that users may have a deep understanding of the hardware
circuitry of the board.
2.2.1 POWER IN
MaaXBoard Mini 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.
