Web232: WebUSB-to-RS232 Board

The Web232 board works as a standard USB-to-RS232 adaptor, but with WebUSB support.

WebUSB JavaScript API allows web-based applications to access USB devices. WebUSB is supported by the Google Chrome browser and is also included in the Chromium open-source browser builds. If you are using Chrome (or a Chromium-based) browser, your web pages will be able to access an RS232 device connected to the Web485 board.
