Most modules have a jumper to switch between "UART" (serial) and "Programmer" (I2C/SPI) modes. For BIOS flashing, ensure the jumper is set to the Programmer pins. 2. Software: The "1.31 Free" and Beyond

| Mode | Function | Common Use | |------|----------|-------------| | | Serial communication (3.3V/5V) | Arduino debugging, console cables for routers | | USB to SPI | Serial Peripheral Interface | Flashing BIOS chips, EEPROMs (e.g., 25 series) | | USB to I2C | Inter-Integrated Circuit | Reading/writing I2C EEPROMs, sensors | | USB to Parallel | Printer port emulation | Legacy hardware control |

The "3" in "3 1" refers to the three primary protocols the CH341 chip can handle: usb drive ch341 3 1

Can act as a programmer for single-chip STC series microcontrollers.

Here is a simplified workflow for doing this: Most modules have a jumper to switch between

rather than a high-speed USB 3.1 storage controller. It is primarily used to bridge USB ports to older or industrial interfaces like UART, I2C, SPI, and parallel ports. Nanjing Qinheng Microelectronics Co., Ltd. Core Technical Capabilities

In this mode, the device acts as a standard USB-to-UART serial adapter. It creates a virtual COM port on your computer. You use this mode to talk to the bootloaders of routers, hard drives, and Arduino boards via standard Transistor-Transistor Logic (TTL) lines. Driver Setup and Installation Software: The "1
