Purpose
Breakout board for the Bosch BME280 sensor. Selectable address and optional pull-up resistors. This looks like a great little sensor and we wanted to try it out!
Purchasing
The dual channel instrumentation amplifier is available through Leeman Geophysical by emailing John R. Leeman at kd5wxb@gmail.com.

Questions
How big is the BME280Breakout PCB?
It measures 20 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BME280Breakout use?
10 parts, built around the BME280. 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 BME280Breakout KiCad files?
From the jrleeman/BME280Breakout repository on GitHub, at the commit this page was made from: the board is KiCAD/bme280_breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BME280Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrleeman before reusing the design.
