This open-source project provides firmware for an ESP32-C3 Super Mini connected to a 1.28″ round GC9A01 display, creating a sonar-style aircraft radar that visualizes live ADS-B data from adsb.fi around the user's location. The device features WiFiManager for easy initial configuration via a captive portal and allows users to cycle through range presets or reset network credentials using hardware buttons.
- Visualizes aircraft with red heading triangles, magenta speed vectors, and callsign tags.
- Supports runway overlays from major airports based on OurAirports data.
- Displays "rim dots" for approaching aircraft located outside the current radar ring but within range of ADS-B data.
- Uses NVS to persist user settings like latitude, longitude, units (mi/km), and WiFi credentials.
