Driver Ch340g ⭐ 💎

| CH340G Pin | Connect To | |------------|-------------| | VCC (5V) | 5V power | | GND | Common ground | | TXD | Microcontroller’s (cross-connect) | | RXD | Microcontroller’s TX (cross-connect) | | DTR | Reset pin (for auto-reset programming) | | XTAL1 & XTAL2 | 12MHz crystal + 22pF caps | | V3 | Decoupling cap to GND (0.1µF) |

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. driver ch340g

If you’ve ever used an Arduino clone, an ESP8266 board, or a cheap logic analyzer, you’ve almost certainly encountered the CH340G . This little 16-pin chip is one of the most common—and most controversial—components in the maker world. | CH340G Pin | Connect To | |------------|-------------|

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). If you’ve ever used an Arduino clone, an
