• Converts a USB mouse to an RS232-output mouse
• Host system does not need USB - it receives RS232
• Works with Microsoft Serial drivers still in Windows (up to Win10) and MS-DOS
• Uses 2-button mouse for movement, buttons, scroll wheel
• Outputs ASCII characters or MS Serial Mouse (Binary) standard or extended Binary output
• E-baud Selectable Baud/Parity from 600 to 115k
• Operates on:
  • 5VDC
  • or 6-12VDC w/optional wall adapter
  • or 4-30VDC w/optional wall adapter

• Systems without USB support, or no HID drivers
• Embedded systems needing mouse input via UART
• Legacy MS Serial Mouse Format systems

       USBM232A is a 2.6" X 1.7" X 0.8" module which provides translation of the USB mouse signals to serial RS232 characters. This allows even small microcontroller systems to incorporate USB mice without any of the development complexity of USB and HID drivers. The RS232 (ASCII or binary) messages for each mouse movement or click are short so as to minimize transfer latency for fast mouse movement.    Manual available here

Works with wired/wireless mice not needing special drivers. Although some mice include a driver CD for special features, many work with default USB drivers and these will work with the USBM232A. Validated with:
