Web232: WebUSB-to-RS232 Board

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

The WebUSB JavaScript API allows web-based applications to access USB devices. WebUSB is supported by Chromium-based web browsers (Chrome, Chromium, Edge, Opera). If you are using Google Chrome or another Chromium-based browser, your web pages will be able to access RS232 devices connected to the Web232 board. This even works on Android smartphones!

Tibbo is making extensive use of the WebUSB functionality. The first example of the Web232 board's usefulness is our PuTTY-like terminal app called WebTerminal.

To aid in the development of web-based apps (HTML pages) supporting the Web232 board, we offer an easy-to-use WebSerial library.
