A messenger which doesn't need wi-fi to operate
LoRa Mesh Messenger is a portable communication device that enables long-range text messaging without any existing infrastructure like cell towers or Wi-Fi. Using LoRa radio technology, it achieves ranges of 2-10 kilometers while consuming minimal power. Each device not only sends and receives messages but also automatically relays messages for other units, creating a self-healing mesh network that extends coverage over vast areas.
Built on the Heltec ESP32 LoRa platform, it features an OLED display for reading messages, simple button controls, and optional GPS for location sharing. The system operates on license-free frequencies and can run for days on a small battery. Ideal for emergency responders, outdoor adventures, remote work sites, and community networks, it provides reliable communication where traditional methods fail. Complete units cost under $30 each, making decentralized messaging accessible for any group needing off-grid connectivity.
