Two-Dimensional Polymer Is A New Ultra-Strong Material 26 Comments Posted in Parts Tagged CH340, CH341, serial, serial adapter, uart, usb, USB to serial Post navigation That can be found with a little bit of Google fu. The driver is a bit more difficult to find, but what you’re looking for is the CH341 family of chips. With ’s help, we now have a cheap source of USB to serial chips. This chip even has an IrDA mode, because wireless communication in the 90s was exactly as rad as you remember. The chip supports 5V and 3.3V, and all the weird modem lines are supported. The CH340 series of chips do exactly what you would expect them to do: a full-speed USB device that emulates a standard serial interface, with speeds from 50bps to 2Mpbs. He got his mitts on a few of these chips and managed to figure out the pinout and a few reference schematics. There is, however, almost no English documentation, and the datasheet for the CH340 family doesn’t include this chip. The cheapest USB to serial chip on the market appears to be the CH340G, available for 20-40 cents apiece from the usual retailers. FTDI-gate wasn’t great for anybody, and now with hardware hobbyists and technological tinkerers moving away from the most popular USB to serial adapter, some other chip has to fill the void.
