Solar Project PreRoute save: common questions
What microcontroller does the Solar Project PreRoute save use?
The Solar Project PreRoute save is built around the ESP32_C3_MINI, from the ESP32 family.
How big is the Solar Project PreRoute save PCB?
The Solar Project PreRoute save measures 100 × 100 mm, has 2 copper layers and is 1.67 mm thick.
How many components are on the Solar Project PreRoute save?
155 components, from 84 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Solar Project PreRoute save design files?
From the Phil-CIA/Solar-Project-200w repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Solar Project PreRoute save design in my own project?
