Mesh Pocket Junior 1.0

The 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 or internet connection.

Overview

Mesh builds are for staying in touch when there's no signal — hiking, festivals, travel, or anywhere off the grid. Instead of a cellular or internet connection, they use a long-range LoRa radio: a group of devices relay each other's messages, so you stay connected across distance.

The Mesh Pocket Junior is the lightest, simplest Mesh build — the same radios as the rest of the family, in the smallest body. There's no keyboard: you type on the touchscreen or from the companion app on your phone, which is what keeps it pocket-sized. It uses the Pocket form factor.

Anatomy & Controls

The Mesh Pocket Junior is three modules stacked into one pocket body — the Core in front, the battery behind it, and the LoRa / GPS radio at the back.

The screen and Core controls:

• A 2.0-inch color touchscreen.
• Five navigation keys: Up · Right · Enter · Left · Down.
• Four buttons on the top edge: L1 · boot · power · R1.
• A small status light — its color and blink pattern depend on the firmware.
• The LoRa antenna screws onto the top — attach it before you use the radio.

Ports and power buttons:

• USB-C on the Core — charges the battery, installs firmware, and connects to a computer.
• A power button on the Core (top edge) and a power button on the battery (its edge) — see First Boot below.

First Boot & Charging

Charge It

Charge through the Core's USB-C port — any standard USB power source works, and you can use the device while it charges. Give a new device a full charge before its first long session.

Power It On

The Mesh Pocket Junior has two power buttons — one on the battery and one on the Core. Because the battery supplies the power, turn it on first.

Using Your Mesh Pocket Junior

A Mesh build communicates over a long-range LoRa radio — no SIM, no internet — and includes GPS positioning. The Mesh Pocket Junior has no keyboard, so you type on the touchscreen or from the companion app on your phone, and read on the screen.

The messaging itself comes from the firmware you install — the software running on your device. Two mesh firmwares you can run are Meshtastic and MeshCore. With a mesh firmware installed, you can:

• Send encrypted text messages across the mesh, fully off-grid.
• Share your GPS position with your group.
• Relay for others — every device extends the network's reach.

Updating Firmware

Your Mesh Pocket Junior can run compatible mesh firmware such as Meshtastic or MeshCore. The easiest way to install or update firmware is the Attaky Firmware Store (fwstore.attaky.com), which runs in your browser — no extra tools to install.

You'll need a USB-C cable that carries data (some are charge-only) and Chrome or Edge on a desktop computer. Connect the Core's USB-C port, choose your firmware, and install it — keep the device connected until it reboots into the new firmware.

Specifications

Safety & Compliance

• Battery — a standard rechargeable lithium cell. Charge from a normal USB source, keep it out of extreme heat, and don't puncture, crush, or open the module. If the battery looks swollen or damaged, stop using it.
• Heat & sunlight — use the device between 0 °C and 40 °C (32–104 °F). Don't leave it for long in hot places such as a parked car, and keep it out of direct sunlight and direct UV.
• Water & moisture — the Mesh Pocket Junior is not waterproof. Keep it dry — away from rain, splashes, and damp places — and don't let water get inside.
• Antenna — like any radio, don't transmit without the LoRa antenna attached.
• Frequency & antenna — your Mesh Pocket Junior ships with a 915 MHz whip antenna and operates at 915 MHz (North America and other 915 MHz regions). Set your firmware's region to match your antenna.

Troubleshooting

• It won't turn on — charge it first (a flat battery won't boot), then hold the power button for about two seconds (not a quick press). Make sure the battery is switched on too.
• It won't charge — charge through the Core's USB-C port with a working cable and a standard USB source. (The battery module's USB-C port only works while the device is off.)
• The Firmware Store can't find your device — use a USB-C cable that carries data (not charge-only), use Chrome or Edge on a desktop, and close any other app connected to the device.
• Messages won't send — make sure the antenna is attached and your firmware's region matches your antenna.
• A feature isn't working — make sure your firmware matches your hardware; mesh messaging needs the LoRa / GPS module.
• Messaging problems — message setup, channels, and contacts are handled by the firmware; see your firmware's documentation.
