WebUSB Boards

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 and RS485 devices connected to the Web232 and Web485 boards, respectively. This even works on Android smartphones!
