SKU CH-ZNVC-EYKM4

A CH340G USB to Mini 5-pin serial cable for 5 V TTL programming and firmware upgrades

  • CH340G chip provides reliable serial communication
  • USB to Mini 5P interface connects legacy devices
  • 5V TTL levels match common microcontroller logic
  • Supports firmware download and upgrade tasks

CH340G USB to Mini 5P Serial Cable

This cable provides a USB to Mini 5P connection with a CH340G chip for 5V TTL serial communication. It is intended for developers and hobbyists who need to flash firmware or debug microcontroller boards that use a Mini 5P header. The link appears as a virtual COM port on the host computer.

CH340G chipset for 5V TTL levels

The CH340G bridge determines voltage logic and driver compatibility, so this cable suits only targets that expect 5 volt signalling. It will not work for 3.3 volt systems or for boards that require a different USB-to-serial protocol. Buyers needing 3.3 volt logic or a Micro USB connector should select another adapter.

Questions about this item

What does the CH340G chip do when I plug this cable into my computer?

The CH340G converts the USB port into a 5 V TTL serial interface so the Mini 5P end can program or debug target hardware.

How does the USB connection limit the serial speed I can use?

The cable uses a USB 2.0 full-speed link, so the practical baud rate ceiling is set by that USB layer rather than the CH340G itself.
