UART to HID Keyboard module
CH9328 is a serial UART to HID keyboard chip that is identified as a standard USB HID keyboard device on computers.
Features:
- Supports 12Mbps full-speed USB device interface, USB 2.0 compatible, built-in crystal oscillator.
- Default serial communication baud rate is 9600bps, which supports multiple serial communication formats and common baud rate settings.
- Supports 5V and 3.3V power supply voltages.
- Supports configuration of VID, PID, and various USB string descriptors of the chip.
- Supports configuration of default baud rate of the chip.
- Complies with USB related specifications and HID device related specifications.
- Multiple operating modes to apply to different requirements, can simulate full keyboard function.
- RoHS compliant SOP16 lead-free package.
For CH9328 V1.4 and above, has integrated crystal oscillator, so X1, C1, C2 are not required and it is recommended to reserve location.
