The LUVI is built with two printed circuit boards:
- the main board which holds all the main components and the display
- the sensor board which holds the UV-sensor
The main components are described on the wiki page UV meter design.
The design is Copyright Enfants de la Lune 2019 - Licenced under the CERN Open Hardware Licence v1.2.
