Overview
Lora is an open-source printed circuit board by GodOfStrategy, from the GodOfStrategy/Personal-LoRa-Puck repository on GitHub. It is a 4-layer board of 40.2 × 53.9 mm with 46 parts on 74 nets, routed with 655 tracks and 285 vias.
It is built around the RP2040, PE4259-63 and SX1262IMLTRT, with the W25Q128JVSIQ, 0900FM15D0039E and AP2112K-3.3 among its other parts. Its parts include 24 capacitors, 7 resistors, 6 ICs, 3 inductors and 2 switches. It belongs with the radio and wireless boards and the RP2040 boards of this library.

README
README.mdPersonal-LoRa-Module
A small compact module made to transmit and receive messages using sub gigahertzs frequencies of radio waves, for use in things such as automation, transmission, reception etc. I wanted to build this for a long time, because I want to implement noise pollution control using these modules, where one module will monitor honking >3 seconds and relay the information of the defaulter's vehicle to the receiver and fine the defaulter.
My LoRa module uses Sub GHz frequencies to tranceive radio waves. It uses the following components:
- SX1262IMLTRT for transmission and reception.
- RP2040 for Programing it for various applications.
- 0900FM15D0039E as an RF filter.
- AP2112K-3.3 as my LDO.
- PE4259 as my RF switch.
- Two quartz timer crystals (12 MHz and 32 MHz).
- SMD Resistors.
- SMD Capacitors.
- SMD Inductors.
- USB-C Receptacle.

Questions
How big is the Lora PCB?
It measures 40.2 × 53.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lora use?
46 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 GodOfStrategy/Personal-LoRa-Puck repository on GitHub, at the commit this page was made from: the board is Production/lora.kicad_pcb and its schematic Production/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 GodOfStrategy before reusing the design.
