Chapter 1. Introduction
This document is the System Reference Manual for BeagleBone AI-64 and covers its use and
design. The board will primarily be referred to in the remainder of this document simply as the
board, although it may also be referred to as AI-64 or BeagleBone AI-64 as a reminder.
This design is subject to change without notice as we will work to keep improving the design as the
product matures based on feedback and experience. Software updates will be frequent and will be
independent of the hardware revisions and as such not result in a change in the revision number.
Make sure you frequently check the BeagleBone AI-64 git repository for the most up to date support
documents.

Chapter 2. Change History
This section describes the change history of this document and board. Document changes are not
always a result of a board change. A board change will always result in a document change.
2.1. Document Change History
This table seeks to keep track of major revision cycles in the documentation. Moving forward, we’ll
seek to align these version numbers across all of the various documentation.

repository. Also check the issues list.
2.2.1. Rev B
We are starting with revision B based on this being an update to the original BeagleBone AI.
However, because this board ended up being so different, we’ve decided to name it BeagleBone AI-
64, rather than simply a new revision. This refers to the Seeed release on 21 Dec 2021 of
"BeagleBone AI-64_SCH_Rev B_211221". This is the initial production release.

Chapter 3. Connecting up your BeagleBone
AI-64
This section provides instructions on how to hook up your board. This beagle requires a 5V ≥ 3A
power supply to work properly via either USB Type-C power adapter or a barrel jack power
adapter.
Recommended adapters:
•5V @ 3A USB C power supply adaptor for SBCs.
•5V ≥ 3A laptop/mobile adaptor with USB-C cable.
All the BeagleBone AI-64 conections ports we will use in this chapter are shown in the figure below.
Figure 1. BeagleBone AI-64 conections ports.
3.1. Methods of operation
1. Tethered to a PC, or
2. As a standalone development platform in a desktop PC configuration with a Display Port
Monitor, power supply, keyboard, and mouse
3.2. What’s In the Box
In the box you will find three main items as shown in BeagleBone AI-64 box image.
•BeagleBone AI-64.
•Instruction card.

Get yourself a USB-A to USB-C and you have a setup for the tethered scenario and creates an out of
box experience where the board can be used immediately with no other equipment needed.
Figure 2. BeagleBone AI-64 box content
3.3. Main Connection Scenarios
This section will describe how to connect the board for use. This section is basically a slightly more
detailed description of the Quick Start Guide that came in the box. There is also a Quick Start Guide
document on the board that should also be referred to. The intent here is that someone looking to
purchase the board will be able to read this section and get a good idea as to what the initial set up
will be like.
The board can be configured in several different ways, but we will discuss the two most common
scenarios as described in the Quick Start Guide card that comes in the box.
•Tethered to a PC via the USB cable
◦Board is accessed as a storage drive and
◦a virtual Ethernet connection.
•Standalone desktop
◦Display
◦Keyboard and mouse
◦External 5V ≥ 3A power supply
Each of these configurations is discussed in general terms in the following sections.
10

3.4. Tethered To A PC
In this configuration, the board is powered by the PC via the provided USB cable—no other cables
are required. The board is accessed either as a USB storage drive or via the browser on the PC. You
need to use either Firefox or Chrome on the PC, Internet Explorer will not work properly. Tethered
Configuration figure shows this configuration.
Figure 3. Tethered Configuration
At least 5V @ 3A is required to power the board, In most cases the PC may not be able to supply
sufficient power for the board. You should always use an external 5V ≥ 3A DC power supply
connected to the barrel jack.
3.4.1. Connect the Cable to the Board
1. Connect the type C USB cable to the board as shown in USB Connection to the Board figure. The
connector is on the top side of the board near barrel jack.

Figure 6. Board Power LED
4. When the board starts to the booting process started by the process of applying power, the LEDs
will come on in sequence as shown in Board Boot Status figure below. It will take a few seconds
for the status LEDs to come on, so be patient. The LEDs will be flashing in an erratic manner as
it begins to boot the Linux kernel.
Figure 7. Board Boot Status
3.4.2. Accessing the Board as a Storage Drive
The board will appear around a USB Storage drive on your PC after the kernel has booted, which
will take a round 10 seconds. The kernel on the board needs to boot before the port gets
13

enumerated. Once the board appears as a storage drive, do the following:
1. Open the USB Drive folder.
2. Click on the file named start.htm
3. The file will be opened by your browser on the PC and you should get a display showing the
Quick Start Guide.
4. Your board is now operational! Follow the instructions on your PC screen.
3.5. Standalone w/Display and Keyboard/Mouse
In this configuration, the board works more like a PC, totally free from any connection to a PC as
shown in Desktop Configuration figure. It allows you to create your code to make the board do
whatever you need it to do. It will however require certain common PC accessories. These
accessories and instructions are described in the following section.
Figure 8. Desktop Configuration
Ethernet cable and M.2 WiFi + Bluetooth card are optional. They can be used if network access
required.
3.5.1. Required Accessories
In order to use the board in this configuration, you will need the following accessories:
•5VDC ≥ 3A power supply.
•Display Port or HDMI monitor.
•miniDP-DP or active miniDP-HDMI cable (or a recommended miniDP-DP or active miniDP-
HDMI adapter https://www.amazon.com/dp/B089GF8M87 has been tested and worked
beautifully.).
14

•USB wired/wireless keyboard and mouse.
•powered USB HUB (OPTIONAL). The board has only two USB Type-A host ports, so you may
need to use a powered USB Hub if you wish to add additional USB devices, such as a USB WiFi
adapter.
•M.2 Bluetooth & WiFi module (OPTIONAL). For wireless connections, a USB WiFi adapter or a
recommended M.2 WiFi module can provide wireless networking.
3.5.2. Connecting Up the Board
1. Connect the miniDP to DP or active miniDP to HDMI cable from your BeagleBone AI-64 to your
monitor.
Figure 9. Connect miniDP-DP or active miniDP-HDMI cable to BeagleBone AI-64

Figure 12. Ethernet Cable Connection
5. The final step is to plug in the DC power supply to the DC power jack as shown in External DC
Power figure below.
Figure 13. External DC Power
6. The cable needed to connect to your display is a miniDP-DP or active miniDP-HDMI. Connect the
miniDP connector end to the board at this time. The connector is on the top side of the board as
shown in miniDP to DP or active miniDP to HDMI connection figure below.
17

Figure 14. Connect miniDP to DP or active miniDP to HDMI Cable to the Board
The connector is fairly robust, but we suggest that you not use the cable as a leash for your
Beagle. Take proper care not to put too much stress on the connector or cable.
7. Booting the Board
As soon as the power is applied to the board, it will start the booting up process. When the
board starts to boot the LEDs will come on. It will take a few seconds for the status LEDs to come
on, so be patient. The LEDs will be flashing in an erratic manner as it boots the Linux kernel.
