ChatterBox: Text Securely Off-Grid

Encrypted local off-grid texting, location sharing, and more. Uses LoRa and smart meshing for local communication. Optional MQTT mesh cloud lets you bridge any distance. Payloads are always end-to-end (device-level) encrypted & signed.

You choose devices, we configure everything. They will arrive ready to run, right out of the box, with no setup needed.

  • Independent of infrastructure & centralized services (cell/internet/grid)

  • Local messaging, broadcasts, & location sharing with trusted people

  • Mesh algorithms forward messages along a smart path utilizing all devices

  • Out-of-range / powered-off devices can receive messages up to 24 hours later

  • Encrypted and digitally signed

Using ChatterBox

ChatterBox is designed for anyone to be able to just pick up and use, intuitively. You don’t need to understand encryption, RF, or configure a bunch of settings, or have an amateur radio license. You don’t need to have a phone or any app.

We strongly recommend buying from us and letting us handle the assembly and configuration for you.

However, if we’re out of stock or you like doing things yourself, you can purchase and assemble devices from elsewhere using the info below. You can also add new devices (acquired from anywhere) to your cluster using the information below.

Communicator

A standard communicator is simply a Lilygo T-Deck Plus running the ChatterBox firmware.

Send encrypted/signed messages, share/track location of other communicators and nodes in your cluster.

Upgraded Communicator

This is big step up, still based on the T-Deck platform by Lilygo. This gives you the ability to easily customize your antenna, higher capacity battery, dedicated realtime clock, and more.

GPS Node

This mesh node performs all mesh functions and also regularly reports its location to the cluster. This could be useful as a fixed or mobile base station.

Proximity Node

A proximity node has all the features of the GPS node, along with an added mmwave proximity/people sensor.

You can be notified of motion via mesh, optionally add a relay switch (you can control remotely), or have it automatically triggered when motion is detected.

E-Paper Mini Node

Considered a top option for a base station, solar setup, or anything that doesn’t need GPS.

OLED Mini Node

Performs slightly better than the E-Paper node, but there isn’t much to the display. Based on the Lilygo T3S3.

Heltec E290 Node

Newest addition, with a 2.9” E-Paper display. Does not use an SD card (only flash).

We can fully assemble and configure your cluster for you. It will arrive ready to power on and use!

Technical

Good place to start if you want to know more.

All messages, locations, and other sensitive information is encrypted during transmission and at rest

All transmitted information is digitally signed, including messages, locations, pings, and delivery confirmations.

Both use LoRa, send messages, and utilize some of the same hardware. That’s where the similarities end.

For enhanced security and anti-jamming, ChatterBox clusters/channels hop unpredictably.
