Project Background

I started by designing a easy LattePanda Mu mini carrier board to verify the key design aspects of various interface modules.

This was my first time designing this type of board. After prototype testing, I found that all interfaces worked normally. Looking back on the entire process, I realized that designing the Mu carrier board and getting it to function properly wasn't as difficult as I had imagined. It mainly requires understanding some wiring standards, paying attention to key points, and having reference examples to learn from.

I will share the design files for this carrier board in this article, hoping it will be helpful to community members.

Feel free to discuss in the comments.

Carrier Board Overview

A easy Mini Carrier, based on the design of LattePanda's official Lite Carrier, with main interfaces including:

• 1x DC Port (12~20V)
• 1x HDMI Port (supports 4K)
• 2x USB 2.0 A Ports
• 2x USB 3.2 Gen 2 A Ports (up to 10Gbps)
• 1x Fan Port (4-Pin)
• 1x Power Button with LED
• 1x M.2 E Key 2230 (PCIe x1, USB 2.0, used for WiFi module)
• 1x M.2 M Key 2280 (PCIe x1, used for NVMe SSD)
