| Market Reality | The CH340G is the USB-serial chip of an entire generation of Arduino-compatible boards, instruments and consumer electronics - the part that made USB-UART cost almost nothing. It is in endless supply, and the practical questions are all about the family: the CH340C removes the external 12MHz crystal (the highest-failure component in the whole circuit) while staying pin-compatible, and the CH340N shrinks to SOP-8 but drops the DTR/RTS handshake lines that reset circuits need. The other classic failure is the V3 pin: a missing or wrong 0.1uF capacitor on V3 at 5V operation is one of the most common reasons a board shows "USB device not recognized". | FT232RL carries a historical premium ($4.50–$6.50/unit) and strict OS driver verification complexities. WCH CH340 series dominates modern USB-to-UART designs globally with proven driver stability across Windows 10/11, macOS, and Linux, and eliminated external crystal requirements on CH340C. |
