Common ICs, particularly around the DIY scene (Arduino, ESP8266, STM32)

  • FT232 (from FTDI)
e.g. on earlier arduinos
  • CH340G / CH340
Driver may or nay not be installed automatically on all OSes, so if not detected you need to find the driver and possibly some instructions.
Datasheet: https://cdn.sparkfun.com/datasheets/Dev/Arduino/Other/CH340DS1.PDF
  • CP2101
exposes a few more pins(verify)
  • PL2303
has a history of knockoffs, and Prolific's Windows drivers changed over time to effectively block these fakes
you can tell if Device Manager shows something like "this is not prolific pl2303 please contact your supplier"
meaning that if you're a DIYer and still want to do something with them, older drivers will work.
