Preparation

Before you begin, please prepare the following:

• A LattePanda Mu or LattePanda Mu Ultra compute module.
• A cooling solution for the compute module. Due to the high thermal density of the Mu Ultra compute module, an active cooler is recommended.
• A power adapter. If you are using the LattePanda Mu compute module, the minimum power requirement is 30W; if you are using the LattePanda Mu Ultra compute module, the minimum power requirement is 50W.
• Peripherals such as a WLAN wireless card, network cable, mouse, keyboard, and display screen.

Installation Guide

1. Open the LattePanda Mu Mini Carrier Board package and remove the carrier board from the anti-static bag.
2. Install any M.2 expansion modules as needed for your actual use, and secure them with the mounting screws.
   
3. Insert the Mu/Mu Ultra (with heatsink installed) into the slot at a 30° angle, press it down, secure it with screws, and connect the fan power.
   
4. Connect peripherals such as a mouse, keyboard, display screen, and network cable according to your actual usage.
   
   
5. Connect the power adapter and press the power button. The first boot may take some time; please wait patiently for 1–2 minutes.

Power Control

The LattePanda Mu Mini Carrier Board supports four power input methods: PD, DC 2.5×5.5mm, DC 2mm, and UPS. You may choose the appropriate method to power your carrier board.

• The DC 2.5×5.5mm power jack and the DC 2mm connector are directly connected. It is strictly prohibited to connect different power sources to both ports simultaneously.
• When using the Mu compute module, the minimum power requirement is 30W.When using the Mu Ultra compute module, the minimum power requirement is 50W

OCuLink Interface

The OCuLink connector is designed for high-performance hardware expansion, providing external devices with a direct PCIe connection to the CPU via high-speed cables.

• The OCuLink interface does not support hot-plugging operations. Before connecting or disconnecting the device, please ensure that the LattePanda power supply is turned off.
• When using Mu, this interface was of PCIe 3.0 x4. When using Mu Ultra, the interface was of PCIe 4.0 x4.

GPIO Pins

There are slight differences in GPIO pins when using the LattePanda Mu versus the LattePanda Mu Ultra.

Frequently Asked Questions

1. Can I directly install and use a previously owned LattePanda Mu compute module?
   Yes, but you will need to update the BIOS of the Mu compute module to unlock all features of the LattePanda Mu Mini Carrier Board.

2. Does the M.2 M Key slot support installing an AI accelerator card?
   No. AI accelerator cards require a special M.2 socket selection and a higher-power design for the power supply.
