Meshtastic is an open-source, off-grid, decentralized, mesh network that runs on affordable and low-power devices. It offers an easy way to connect and communicate with others. To get started, you need to purchase the supported hardware like a radio, battery case, and antenna. The quality of the antenna can vary, so it’s important to choose a reliable supplier. The next step is to flash and configure the node using the Meshtastic Web-Based Flasher & Clients, which simplifies the process. Finally, there are different applications available for Android, iOS, Mac, and web browsers to connect to the node. This technology is unique and clever, allowing for independent communication without relying on traditional networks.
