flat_sat_dev_board
This board is intended to be a "FlatSat" stand in for all of the core hardware of the PROVES Kit! By putting all of the microcontrollers, sensors, and communications hardware on one convenient board you can carry it around with you where ever you'd like!
Find a link to the documentation for that here!
Camera_board_v2
This board is currently being developed for the Irvington High School Girls in STEM Club team, who are looking to fly a camera on Pleiades - Orpheus.
Mux_driver_board_v1
This board is a breakout hosting both the TCA I2C Multiplexer and an I2C based LED driver. It is intended to be mounted as a daughter card on another PCB and used to provide access to additional protected I2C buses.
FC_Advanced_Carrier
This is the initial design for a board that is able to accept an NVIDIA Jetson Nano SoM.

Questions
How big is the Hat board PCB?
It measures 106.5 × 99 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hat board use?
108 parts, built around the DRV2605LDGS, TMP112AIDRLR(UMW), VEML7700-TT and TCA4311AD. 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 Hat board KiCad files?
From the proveskit/development_boards repository on GitHub, at the commit this page was made from: the board is HatBoard/hat_board.kicad_pcb and its schematic Archive/Camera_board_v1/camera_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hat board design in my own project?
Its repository states no licence, so its author keeps all rights: ask proveskit before reusing the design.
