Segger emWeb offers a new, easy way to configure a device that does not have a display, i.e. a headless device. Connecting a device that does not have a human interface is now as easy as plugging in a cable. emWeb uses a USB charging port to connect to a PC, enabling configuration within the comfort of a web browser.
This technology is easily accessible for all USB devices, enhancing their value and ease of use. There is no need for buttons or a display on the unit, as any PC can operate the device.
One example is a printer. Instead of the usual mini touch screen, emWeb via USB enables a printer to be headless. Connecting a printer via USB allows the user to configure WiFi or IP address, paper type and print quality, status information, etc., all on a PC's large screen. This saves the manufacturer the cost of a display, plus the design headache of where it should be placed, while also enhancing the user experience.
Almost any IoT device with a USB port may benefit from emWeb to improve and simplify its human interface. The company uses the same technology in its marketing-leading J-Link debug probes. Headphones, speakers, a solar inverter, and many other products come to mind.
