Open-source LoRa mesh messaging without Wi-Fi, GSM, or Internet.
Custom hardware • Mesh firmware • Flutter chat app
LoRaptor is an open-source LoRa P2P mesh messaging platform built for off-grid communication. It combines a custom hardware node, embedded firmware, and a companion app so a paired phone or computer can send messages through a LoRa mesh network.
- LoRa mesh communication for off-grid messaging
- Custom ESP32-S3 + RA-02 based hardware
- BLE and USB connectivity
- AES-128 encrypted messages with payload compression
- RaptorCLI for terminal-based control
- RaptChat app for pairing, configuration, and chat
LoRaptor uses a compact custom PCB designed around the ESP32-S3-MINI-1 and RA-02 LoRa module, with USB-C, RGB status signaling, and a portable 3D-printed enclosure.
The firmware is built around LoRaMesher for mesh routing and RaptorCLI for device control over BLE or USB.
