o Note: “Lite” versions of the Compute Module 4 without onboard eMMC Flash memory

are not supported.

• Internet connection

• LAN hub and standard network cables

• Standard USB 2.0 or 3.x cable (USB to USB Micro-B) for programming.

Lengths of up to 10 feet or 2.5 M can be used with high quality USB cables.

• Host PC running either Windows, macOS, or Ubuntu, or a standard Raspberry Pi 1 / 2 / 3 / 4

running Raspberry Pi OS

• USB keyboard and mouse for connecting to the display (recommended)

• Operating system

• Software configuration tools (see following sections)

Important Cautions

• Always disconnect the display from AC power when inserting or removing the Interface Board

from the display.

• The two sets of connectors on the Compute Module 4 and the Interface Board are very fragile

and are rated at about 30 insertions maximum. Therefore, do not mate and un-mate the two

unnecessarily.

• When mating the Compute Module 4 to the Interface Board pay careful attention to the

orientation of the Compute Module.

• The included heatsink should be attached to the Compute Module after testing and before final

installation to provide cooling for the Compute Module. The included thermal conductive sheet

should always be used between the heatsink and the Compute Module.

• Disconnect the programming USB Micro-B cable from the Interface Board when programing is

complete. Leaving it connected will result in the USB ports and internal 10/100 LAN being

inactive.

About Wireless Connectivity (Wi-Fi and Bluetooth)

• The DS1-IF21CE interface board together with a wireless enabled version of the Compute

Module 4 and external antenna kit can be used for Wi-Fi functionality. At the time of writing,

Bluetooth functionality is disabled pending regulatory approvals. See the relevant sections of

this guide for information on installing and configuring the wireless functions.

• An external USB wireless adapter “dongle” can be used can be used with either the DS1-IF20CE

or DS1-IF21CE Interface Boards to provide wireless functions.
