Overview
The processing board is responsible for the main processing of the vibration analysis. On board is the ATmega328pb microcontroller, RFM95W LoRa transceiver and ADXL362 accelerometer. In addition there is a NMOS low side switch to turn of the RFM95W and ADXL362 when they are not needed to save power consumption.

Questions
What parts does the Foresight processing use?
57 parts, built around the ATMEGA328PB-AU, ADXL362BCCZ-RL7, RFM95W-915S2 and BSS138. 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 Foresight processing KiCad files?
From the nuzzer25/foresight-processing repository on GitHub, at the commit this page was made from: the board is foresight-processing/foresight-processing.kicad_pcb and its schematic foresight-processing/foresight-processing.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Foresight processing design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
