Outage ready
Small radio nodes can relay short messages across neighborhoods without depending on cell towers or home internet.
Community-owned communication
Stay connected when the internet is down.
A3Mesh is building a resilient MeshCore network across Manor, Elgin, Bastrop, Austin, and the wider Central Texas corridor.

Why A3Mesh exists
Local communication should not disappear during outages.
Community owned
Residents, volunteers, and local organizations host nodes so coverage grows with the people who use it.
Built to expand
The first corridor connects east of Austin, then grows toward San Antonio, Dallas, Houston, and rural communities between them.
MeshCore project
A3Mesh is building its first network on MeshCore.
MeshCore is an open-source LoRa mesh project for long-range, low-power communication without depending on cell service, Wi-Fi, or traditional internet infrastructure.
Simple messaging
Neighbors can send short messages through nearby nodes, relays, and handheld devices instead of relying only on phones and towers.
Real local coverage
A3Mesh will focus on useful coverage first: homes, farms, parks, shops, community spaces, and routes between Central Texas towns.
Open hardware path
The network can grow with affordable LoRa devices like Heltec boards, RAK kits, and LILYGO handheld communicators.
Network plan
Start with reliable local hops, then link towns together.
A3Mesh focuses on practical relay points, good antennas, and enough nearby nodes that the network is useful before it becomes large.

How it works
Three simple ways to help the mesh become real.
Install a node
Host a small MeshCore-compatible LoRa device at home, work, or a high point with clear coverage.
Invite neighbors
More nearby nodes means stronger local reach, better routing, and a network people can actually rely on.
Build relays
Volunteer relay sites connect towns, parks, farms, businesses, and emergency gathering places.
A3Mesh hardware
Choose the device that fits your MeshCore node.
A3Mesh starts with proven LoRa mesh hardware: compact boards for testing, modular kits for relays, and handheld communicators for the field.
Starter board
Heltec WiFi LoRa 32 V4
A compact ESP32-S3 LoRa board for low-cost testing, window nodes, portable builds, and first A3Mesh experiments.
- Good first device for makers
- Small OLED display on board
- Wi-Fi, Bluetooth, and LoRa
- Works well with printed cases
Relay kit
RAK WisMesh Starter Kit
A modular kit for stable router, relay, tracker, and solar-ready node builds where reliability matters.
- Modular WisBlock ecosystem
- Good for outdoor enclosures
- Expandable with sensors or GPS
- Strong choice for fixed relays
Handheld
LILYGO T-Deck
A pocket communicator with screen, keyboard, and LoRa radio for people who want a standalone messaging device.
- Built-in keyboard and display
- Useful for field communication
- Works without a full laptop
- Good demo device for meetups
Reticulum support is coming soon.
Get involved
Host a node, volunteer, or follow the rollout.
The first version of A3Mesh needs practical people: node hosts, antenna builders, neighborhood organizers, website contributors, and nonprofit supporters.
