Mesh Deck Junior 1.0
The flagship off-grid communicator — long-range LoRa messaging with a full QWERTY keyboard built in.
Mesh Deck Junior 1.0 is the flagship of the Mesh Series — a complete, pocket-sized off-grid communicator with a real keyboard. It pairs a long-range LoRa radio and GPS with a color touchscreen and a full QWERTY keyboard, so you can send messages and share your location with no cell network, no Wi-Fi, and no internet.
What makes it the flagship is the keyboard: where the other Mesh builds lean on a phone or on-screen input, Mesh Deck Junior lets you touch-type real messages right on the device — fast, and entirely self-contained.

What you can do with it
- Send encrypted text messages across the mesh, fully off-grid
- Share your live GPS position across the mesh — and see everyone on the map in the companion app
- Type fast on the built-in QWERTY keyboard
- Relay for others — every device extends the network's reach
- Go all day on a charge with normal use, with no tether
What's in it
- Core: ESP32 1.0 — the host: 2.0-inch color touchscreen, Wi-Fi, Bluetooth
- Expand: LoRa / GPS 1.0 — long-range radio + GPS for off-grid mesh
- Control: Keyboard (Bottom) 1.0 — a full QWERTY keyboard for typing
- Power: Standard Cell 1.0 — the rechargeable battery
- A Deck Frame that holds the modules together, plus the linking cables
What it's for
Mesh Deck Junior is for staying in touch when there's no signal — hiking, festivals, travel, emergencies, or anywhere off the grid. The keyboard makes it the one to pick when you'll actually be typing: a campsite group chat, a set of coordinates, a quick note to another node.
It's built for off-grid mesh communication: flash a mesh firmware and devices relay each other's messages, so a group stays connected across distance, and each one can share its GPS position across the mesh. Meshtastic and MeshCore are mesh firmware you can run on it — see Firmware for the options.
Power it on
An Attaky has two power buttons — one on the battery and one on the host (Core). Switch the battery on first, then the Core.
These are close-ups of the modules — the power buttons are the same on every build.

Good to know
The keyboard is what sets it apart. Same radios as the other Mesh builds, but with a real keyboard you can touch-type on — the flagship pick for messaging.
Built as a Deck. The upper section is the Core with the LoRa / GPS radio behind it; the lower section is the keyboard and the battery. The battery connects to the Core by a 7-pin power cable and the keyboard by a 12-pin FPC cable — all held in one Deck Frame. The datasheet has the full breakdown.
Attach the antenna before transmitting. Like any radio, don't transmit without the LoRa antenna attached.
Region & frequency. Ships as a 915 MHz version for North America. 868 MHz (EU / India) and 433 MHz (EU / China) versions are coming. Each radio is tuned for one band — match your firmware's region setting to it.
Battery. Expect about a day of normal use on a charge; it depends on how much you transmit and how bright the screen is.
Keep it dry and cool. It isn't waterproof — keep it away from rain, splashes, and damp. Operating temperature is 0–40 °C (32–104 °F); keep it out of direct sunlight and prolonged heat, and do not leave it in a parked car.
Size — 68 × 97 × 29.8 mm (250.5 mm tall with the antenna up), 156.8 g.
