Using this repo
using your favorite package manager, install kicad-footprints and kicad-symbols alongside kicad. this is the best way to get the standard libraries. if you for some reason cannot do so, see the linked official kicad libraries in kicad-libs/footprints and kicad-libs/symbols. in the kicad symbol editor, go to preferences -> manage symbol libraries and select "add existing", navigate to the kicad-libs/symbols directory and select the symbol libraries contained therein. repeat this with the symbols contained in kicad-libs/JLCPCB-Kicad-Library. repeat this for footprints.

docs
will add as much documentation as possible!
Node V6 (RP2040)
changes:
- removed 5v regulator
- changed rp2040 xtal to the recommended part due to availability
- changed the sim card slot due to availability
- reviewed other parts and made changes to ensure full availability from both JLC and Digikey
- changed footprints over to JLC library footprints
- major layout changes- pin headers now broken out in two halves, etc - look at the pcb for a full description
- removed jst connectors (evil) and replaced them with barrel jacks
- mounting holes now m2.5 instead of m2
Node V5 (RP2040)
SIM7080G NON-FUNCTIONAL
change since previous version:
- added USBLC6 esd protection on the usb line
- added CAT24 eeprom ic
- removed options for rtc to stick with just the PCF8523
- added SP3485 for RS485 / MODBUS communication
- added u.fl connector for the ism radio
- changed to narrower profile pushbuttons for run/bootsel
- added additional reset switch to interrupt 3.3V to the board entirely (used to reset the device to a known state for all components including the radios)
- yet more improvements to routing
- updated design to be mostly assembled by JLC pcb fab available components

Questions
How big is the Node v6 2 0 PCB?
It measures 45 × 75 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Node v6 2 0 use?
100 parts, built around the RP2040, SIM7080G, AP2112K-3.3 and PCF8523T. 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 Node v6 2 0 KiCad files?
From the VTC-WISDOM/node_hardware repository on GitHub, at the commit this page was made from: the board is node-rp2040/node_v6_2_0/node_v6_2_0.kicad_pcb and its schematic antennas/915-yagi/915-yagi-v2/yagi/yagi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Node v6 2 0 design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
