But measuring length is not the only ability of the device. It is also capable of measuring ambient noise and lighting. Roulette is equipped with a screen with a diagonal of 1.9 inches and lead only 30 g. The built-in battery lasts up to 3000 measurements. Curiously, the USB-C port is used for charging. And this is when some manufacturers continue to use micro-USB in much more expensive devices.
A small part of the wheel – the so-called digital encoder – is used to project the measurement process from the side wall. It is characterized by high precision and sent to the small STM32 processor for processing. In addition to evaluating the measured distance, it also manages unit conversions and simple conversions. All necessary data is shown on the display.
