## What it is
SoftRF is a DIY, multi-functional sub-1 GHz ISM band radio proximity awareness system for general aviation, compatible with protocols like FLARM, ADS-B, OGN, and APRS. It runs on ESP32 and other embedded hardware in multiple wearable and portable editions for pilots of gliders, paragliders, and UAVs.

## Use cases
- build a DIY FLARM-compatible traffic awareness device for gliding
- receive ADS-B and OGN aircraft traffic on a wearable badge
- add proximity warning to a paraglider or UAV with MAVLink
- track nearby aircraft using LoRa radio while soaring
- experiment with aviation transponder protocols on ESP32 hardware

## When to choose
- you want an open, compatible DIY alternative to commercial FLARM/ADS-B receivers
- you fly gliders, paragliders, or drones and need low-cost traffic awareness
- you enjoy building embedded hardware projects with ESP32 or nRF chips

## When to avoid
- you need a certified, plug-and-play commercial avionics device
- you have no interest in assembling or flashing your own hardware
- you need certified equipment for regulated airspace requirements

## Facets
