Proudly fiscally hosted by Open Source Collective. Your 501(c)(3) tax-deductible donations directly support open-source civil defense.
Real-time spectral analysis runs entirely on the ESP32-S3. No cloud round-trips, no latency — detection in milliseconds.
AES-128-GCM encrypted packets over LoRa sub-GHz. Designed for contested RF environments with anti-jamming resilience.
MQTT auto-discovery means plug-and-play integration. Trigger automations, log events, and monitor your airspace from your dashboard.
Supports Heltec WiFi LoRa 32 V3 out of the box, with a board abstraction layer ready for LILYGO PoE and other ESP32-S3 variants.
Batear is being field-tested in collaboration with Ukrainian defense experts in active electronic warfare environments. Our partners' identities remain confidential for their safety.
What the community is saying about Batear.
A "retrovation" inspired by WWII-era acoustic aircraft detectors — edge-only processing at just $15 per node.
Adafruit spotlights Batear as an accessible, open-source approach to drone detection for makers and civil defense.
Focusing on the efficiency of edge detection — no internet, no cloud, no subscription — suitable for off-grid deployments.
