For the selection of modules, you can refer to the instructions of the data manual.You can tell your customer service directly if you don't know if the module meets your needs. Customer service will choose the appropriate module according to your needs!

If the module is used with serial port equipment such as single -chip microcomputers, you can directly use the needle pin from the module to be used on the microcontroller serial port;The upper machine software configuration module needs to be used with the USB to TTL module!

CH9329 is a serial transfer standard USB HID device (keyboard, mouse, custom HID) chip. According to different working modes, it can be recognized as a standard USB keyboard device, USB mouse device or custom HID device on the computer.The chip receives serial data sent by the client, and according to the HID device specifications, the data is packed first and then passed to the computer through the USB port.Through the provided upper machine software, users can also configure the chip working mode, serial communication mode, serial port communication Potter rate, various timeout time, VID, PID, and various USB string descriptive symbols.The figure below shows its general application box diagram.

Note: Use the upper machine test software to use the USB to TTL module!
