: Keep a few CH340G modules in your parts drawer. And keep the driver installer on a USB stick. You’ll thank yourself later. Have you had a CH340 driver nightmare or a perfect experience? Drop a comment below!

Yes, drivers can be annoying. Yes, it’s not an FTDI. But for 95% of hobbyist projects—blinking LEDs, reading sensors, flashing ESPs—the CH340G works just fine.

Love it or hate it, the CH340G is everywhere. Today, let’s break down what it is, why you keep seeing it, and how to use it successfully. The CH340G is a USB-to-serial UART converter manufactured by a Chinese company called WCH (Nanjing Qinheng Microelectronics). Its job is simple: convert data between a computer’s USB port (modern) and a microcontroller’s serial UART pins (legacy, but still universal).
