• Converts a USB mouse to an RS232-output mouse
• Your system does not need USB .. it receives RS232 characters
• Uses a 2-button mouse for x-y movement, buttons clicks and scroll wheel
• Outputs ASCII characters or MS Serial Mouse standard or extended output
• RS-232 Connection To Host W/Selectable Baud/Parity. Baud rates 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

       USBM232 is a 2.6" X 1.7" X 0.8" module which provides translation of the wired 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

Typically works with all wired mice which do NOT require special drivers to operate on a PC. Although some mice include a driver CD for special features, many work with the default Microsoft OS USB drivers and these will work with the USBM232. Validated with:
