Everything you need.And then some.

Stay connected

Mobile networks, Wi-Fi and Bluetooth keep you connected every day. Long-range radio keeps your group in touch across kilometres—while travelling, off-grid or in an emergency.

Keep things running

Run Poketron on battery power wherever you go or through an outage, and share power with other USB-C devices.

Watch over things

Record with the Raspberry Pi camera, locally or over 4G with the Radio board, or keep an eye on a bag and other valuables.

A server that travels

Carry your files and run a lightweight server wherever the device goes. Its battery can keep both available through an outage.

Listen to the airwaves

Tune into FM, amateur radio and compatible satellite signals from 30 MHz to 2 GHz with the receiver version of the Radio board.

Build and automate

Build custom devices around a repairable, battery-backed Linux platform with open hardware you can change.

Carefully specified.

Size
120 × 80 × 31 mm.
Weight
Approximately 400 g including batteries (estimate).
Compute
Raspberry Pi Zero 2 W for Linux applications. A small always-on controller runs the power bank and power-up on its own, so the device works even with the Pi switched off.
Storage
Replaceable microSD card in the Raspberry Pi.
Network
Wi-Fi and Bluetooth LE on the Raspberry Pi and built-in LoRa. 4G LTE with an eSIM, and GPS, on the optional Radio board.
Power
Two replaceable 21700-format cells with protection and a fuel gauge. USB-C charging from 1.5 A or 3 A chargers, and power-bank output to other USB-C devices.
Protection
Designed to resist water and dust, targeting IP67, with sealed screw wells and screwed, gasketed USB-C fittings. Not yet tested.
Radio
LoRa at 868 MHz, up to +22 dBm, is built in. The receiver version of the Radio board, fitted in place of the 4G one, tunes 30 MHz to 2 GHz.
Interface
3.7-inch touch e-paper display, a speaker, stereo microphones, a sealed USB-C port on each side, one for charging and one for power-bank output and USB accessories, and a button on each side.
Camera
Raspberry Pi camera connection.
Construction
A durable polymer enclosure with an integral rear, top and bottom. Six sealed screw wells are printed in one piece with the cradle for the two cells. Common M3 screws secure the inset front plate for servicing.
