We have developed our own PCB using LP4, referencing your K230 V3.0 PCB design from EasyEDA. However, we are currently facing an issue where the USB port is not being detected in the Device Manager of our laptop.
We have followed the provided design and connected a memory card with the given image, but the board is still not recognizing the USB connection. To assist in troubleshooting, we are attaching our schematic for your review. Additionally, we are sharing the details of the reference design we used:
Reference File: CanMV-K230 V3.0开发板原理图和PCB设计文件
MD5 Download Date: 2023-08-21
Version: 3.0
Although we did not use EasyEDA for our board design, we closely followed the EasyEDA PCB design reference available on your support portal.
We are burning the following image onto the SD card:
