README
README.mdMeshing the LoRa
This is a compact LoRa puck for all your needs such as meshtastic. I made this because I'm on my way to getting my ham radio licence and I thought this would be a cool accompanying thing. (also meshtastic is peak)
Where did this name come from?
I intend to use it for meshtastic so I thought of this name!

Questions
How big is the Lora PCB?
It measures 27.1 × 70.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lora use?
71 parts, built around the RP2040, PE4259-63, SX1262IMLTRT and W25Q128JVSIQ. 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 Lora KiCad files?
From the frogtospace/Meshing-the-lora repository on GitHub, at the commit this page was made from: the board is kicad/Lora.kicad_pcb and its schematic kicad/Lora.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lora design in my own project?
Its repository states no licence, so its author keeps all rights: ask frogtospace before reusing the design.
