README
README.mdDRF1278F and XL1278-SMT LoRa breakout board
A somewhat 'universal' breakout board to adapt Dorji DRF1278F and XL1278-SMT modules to standard 0.1" matrix breadboard or stripboard format.
Module identification
Note: while the DRF1278F and XL1278-SMT boards look similar, the pinouts are significantly different.
Confusion
There is a lot of confusion between Ebay and AliExpress sellers alike. One ebay seller even showing photos of both types of boards on the same listing. So check carefully, or use what you're given with this either/or breakout.

Questions
How big is the Universal 1278 breakout PCB?
It measures 26.7 × 30.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Universal 1278 breakout use?
6 parts. 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 Universal 1278 breakout KiCad files?
From the matburnham/lora-breakout repository on GitHub, at the commit this page was made from: the board is Hardware/Universal 1278 breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Universal 1278 breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask matburnham before reusing the design.
