This is a 10x10mm USB-Uart converter with 2Mbps interface speed based on the cheap CN330. Source files available on GitHub.

CH330(N) works with CH340/CH341 driver as pointed out by Icenowy Zheng who made a small USB to TTL debug board based on the chip to practice PCB drawing with KiCAD. She also mentioned the USB ID and behavior of CH330 is the same with CH340.
