Projects & Structure
Firmware
This folder contains all of the Embedded and C projects that will be flashed to the devices operating on the farm
Firmware / PAM
The Firmware that runs on the 2B Tech PAM device
Firmware / MKR
The Firmware that runs on the Arduino MKR board on the 2B Tech PAM, which provides cellular services
Cloud
All of the code that has been deployed to GCP
Cloud / Cloud-Functions
Cloud Functions! These are exposed via an HTTP endpoint that GCP manages for us, and run in response to an HTTP request
Cloud / Cloud-Functions / hologram-ingest
When the PAM uploads data, it is first sent to Hologram through their Embedded Socket API. This is a low overhead protocol that minimizes bandwidth from our embedded device. Hologram then sends the data to a webhook that we have defined. In this case, the webhook is this Cloud Function. The Cloud Function simply takes the data sent from Hologram and inserts it into a raw table in BigQuery (sensors_v1.raw_backpack_v1).
Cloud / Cloud-Run
Cloud Run Jobs!
Cloud / Cloud-Run / hologram-transform
This Cloud Run job is triggered nightly be an associated Cloud Scheduled Trigger. The job is responisble for taking the data that was inserted into raw_backpack_v1 during the previous day and inserting it into backpack_data_v1. This second table has a schema that represents the data that was collected, rather than the data that was uploaded to Hologram.

Questions
How big is the Dboards-02 PCB?
It measures 426 × 182.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dboards-02 use?
371 parts, built around the P82B96D, AP2127K-1.8TRG1, ICM-20948 and SDP31. 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 Dboards-02 KiCad files?
From the QuantumMatter/Rumission repository on GitHub, at the commit this page was made from: the board is Hardware/Daughter Boards/dboards-02/dboards-02.kicad_pcb and its schematic Hardware/Daughter Boards/dboards-02/10_main_root.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dboards-02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask QuantumMatter before reusing the design.
