README
README.mdSolarcast
Safecast Solarcast sensor device is designed to operate off-grid and sense environmental parameters. It consists of 5 key modules designed for maximal reuse.
Modular design
In an optimal design all modules have their own BLE processor and can be directly combined between each other, initial design is however only partially modular.
Design parameters
The PCBs have to be designed in KiCad package.

Questions
How big is the Communications module PCB?
It measures 125.8 × 128.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Communications module use?
76 parts, built around the BME280, TPS2066D, SN74LV4052AD and JUMPER3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Communications module KiCad files?
From the Safecast/Solarcast repository on GitHub, at the commit this page was made from: the board is communications-module/kicad/communications-module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Communications module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Safecast before reusing the design.
