That is looking very nice indeed.

Do you have hardware tests of the fastest UART BAUD speeds without dropping or losing bytes ?
eg a FT232H talking to this, how fast can the link sustain continual TX/RX ?

Can DTR/RTS be enabled to improve highest speeds ?

Q：
这看起来确实很漂亮。
你们有对最快的UART波特率进行硬件测试，以确保不会出现数据丢失或损坏的情况吗？例如，FT232H与该设备通信时，链接能够持续进行传输和接收的最高速度是多少？
是否可以启用DTR/RTS功能以提高最高传输速度？

A：
最高支持10M波特率
10M波特率发送大文件（一个PDF文件）测试：

官方固件无DTR/RTS功能，但一箭双雕开源例程中有（A2、A3），可以修改IO口后重新编译下载实现

T：
The highest supported baud rate is 10M.
10Mbps transmission of large files (a PDF file) test:

The official firmware does not have DTR/RTS functionality, but there are open-source examples (A2, A3) with this feature that can be modified and recompiled for download to achieve the same result.
