The project uses XT60 conenctor for battery input and screw terminals for ESCs output. The board idea is to have fuse, current measurement, and buck converter to 5V. Curent measuremnt from INA amp is sent to FCU, mounted above, with JST-XH conenctor together with 5V, VBAT voltage measurement, and GND.

Questions
How big is the PDU v2 PCB?
It measures 67.6 × 60.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PDU v2 use?
71 parts, built around the INA240A2D, XT60PW-M, SF-2923HC30C-2 and SMCJ28A. 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 PDU v2 KiCad files?
From the Fred0809/PDB repository on GitHub, at the commit this page was made from: the board is PCB/PDU_v2/PDU_v2.kicad_pcb and its schematic PCB/PDU_v1/PDU_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PDU v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fred0809 before reusing the design.
