Mesh Pocket Junior 1.0
The simplest way onto the mesh — long-range LoRa messaging and GPS in a pocket-sized handheld, no keyboard, no tether.
Mesh Pocket Junior 1.0 is the entry point to the Mesh Series — a compact, pocket-sized off-grid communicator. It pairs a long-range LoRa radio and GPS with a color touchscreen, so you can send messages and share your location with no cell network, no Wi-Fi, and no internet.
It's the lightest, simplest Mesh build: the same radios as the rest of the family, with the smallest footprint. You drive it from the touchscreen and Core's onboard keys, or pair it with the companion app on your phone — there's no built-in keyboard, which is what keeps it small.

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
- Relay for others — every device extends the network's reach
- Slip it in a pocket and go all day on a charge with normal use — 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
- Power: Standard Cell 1.0 — the rechargeable battery
- A Pocket Frame that holds the three modules together — they stack back-to-back, no cables
What it's for
Mesh Pocket Junior is for staying in touch when there's no signal — hiking, festivals, travel, emergencies, or anywhere off the grid. It's the one to pick when you want the lightest, most pocketable way onto the mesh and you're happy typing on-screen or from your phone. Want a built-in keyboard for fast messaging? That's Mesh Deck Junior.
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 smallest, lightest Mesh build. Same LoRa radio and GPS as Mesh Deck Junior and Mesh Station Junior, with the smallest footprint and no keyboard — the most portable way to carry the mesh. It is a little thicker than Mesh Deck Junior, though: without a separate keyboard section, the three modules stack front-to-back.
Built as a stack. The three modules join module-to-module — the Core in front, the battery behind it, and the LoRa / GPS radio at the back — all held in one Pocket Frame. No linking cables. 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 — 48 × 68 × 39.6 mm (229.5 mm tall with the antenna up), 121.5 g.
