README
README.mdfantastic-node
A meshtastic node designed to be self sufficient (solar powered) and small/unnoticeable enough to be planted in urban spaces.
I think that mestastic is a great project aiming at making an offgrid network of devices allowing for communication but as part of how it operates, it is limited by the cost and ease of implementing these community ran nodes transmitting packets across a city for instance.
In this repo, you will find a pcb meant to be affordable, with a 3d printable case and easily sourcable parts.

Assembly
- Assemble the pcb put all components together and soldere them using the schematic
- Print the case+parts and glue the solar pannel in place then place all heat inserts in holes
- Build the firmware following meshtastic instructions using files in /firmware/* and flash with usb !
- Put the board and wire antenna plug connect battery to terminals to test out if working and then glue the battery and screw everything together. Use the f3d file to help with assembly :3 (will add more details and pics once i make it)

Questions
How big is the Node PCB?
It measures 31.7 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Node use?
22 parts, built around the VGDD79S868N0S1, CN3163 and DW01A. 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 KiCad files?
From the LJBoxx/fantastic-node repository on GitHub, at the commit this page was made from: the board is hardware/kicad/node.kicad_pcb and its schematic hardware/kicad/node.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Node 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).
