Where can I find information on the firmware and hardware version of a device?

Open get red-y and after your device has been recognized, select the menu “Overview”.

get red-y Software – Firmware & Hardware

In the above example the device has FW version 6.1.09 and the hardware board version 6.0.03 (often documented as 6.0.3).
