PCB designed with KiCad, assembled by seeedstudio (https://github.com/Seeed-Studio)
Next steps todo:
- testing low power consumption (low current measurement equipment needed like https://github.com/nfhw/tinycurrent)
- rework pcb to shrink it
- connection to Datacake instead of directly to Helium

Questions
How big is the LoRa E5 BME680 PCB?
It measures 50 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoRa E5 BME680 use?
13 parts, built around the LORA-E5-HF, BME680, 0868AT43A0020E and MY-2450-01. 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 LoRa E5 BME680 KiCad files?
From the johflo/Seeed-LoRa-E5_BME680 repository on GitHub, at the commit this page was made from: the board is HW/LoRa-E5_BME680.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRa E5 BME680 design in my own project?
Its repository states no licence, so its author keeps all rights: ask johflo before reusing the design.
