Hi I've a nrf52840 DK and SDK 15.3.0. I'm using USB CDC ACM example. When I use Windows 7 to connect to the USB port, it kind of detects the device, but the device manager shows Yellow mark, telling me the device is not properly installed. Has anyone tried SDK 15.3.0 with the DK? Any suggestions on the example project?

Hi,

Order a new nRF52840 DK. The preview kits contains early engineering samples before the chip was qualified and put to production.

Best regards,
Kenneth
