This build redefines what a router can be. Haven is an open-source, portable Wi-Fi HaLow mesh router that runs on a Raspberry Pi 4, capable of linking devices over kilometers without internet or subscriptions. It uses the same sub-GHz spectrum as LoRa and Meshtastic but supports full IP networking — meaning all your regular apps just work. Built entirely from open hardware and open firmware, Haven runs 802.11s + BATMAN for self-healing, peer-to-peer communication you truly own.
