This is the CH340G USB to UART chip that is at the core of my M180 Seires USB to UART adapter. I am making this chip available here, with translated datasheet, for your convenience.

Due to Tindie not allowing unit prices lower than 1 dollar, I have to sell this as packs of two. Consider it one for your project and one spare if you made a mistake soldering it.

The "number in stock" represents how much I currently have. If you want to order more, contact me so I can increase the stock number to allow you to order, and start sourcing the chips for you.

If you need lots of this chip, you may have to wait about a week before I can ship it out - I don't keep large stocks and to fulfill large orders I will have to source it too, from local market if the order is small, and from WCH directly if the order is big.

If you need a ready-made module, here is an option.

The usual warranty policies does not apply to this. You can only return and refund unused chips, that is, not soldered.
