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

Use local or 4G camera recording, a body camera or a movement alarm for 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, and pick up signals from nearby transmitters with a separate receiver.

Build and automate

Build custom devices around a repairable, battery-backed platform. Add an external robotics controller through a general-purpose interface.

Carefully specified.

Size
120 × 80 × 31 mm.
Weight
Approximately 400 g including batteries.
Compute
The STM32H753 application controller works independently. The modular compute bay can house a Raspberry Pi Zero 2 W or a custom PCB.
Storage
Storage and logging use the Raspberry Pi. Pi Zero uses replaceable microSD storage.
Network
4G LTE, Wi-Fi, Bluetooth LE and LoRa, with eSIM planned.
Power
Two replaceable 21700-format cells, up to 30 W USB-C charging and protected power-bank output. The power system works independently of the computer.
Protection
Designed to resist water and dust, targeting IP67.
Radio
GNSS and LoRa are built in. A removable receiver-only SDR is planned for later FM and 42–1002 MHz reception.
Interface
E-paper touchscreen, optional voice input, NFC and two bottom USB-C ports with a round power button between them. Four-port USB 3.2 Gen 1 base hub support is available for internal expansion. A SuperSpeed host can use 5 Gbit/s; Pi Zero 2 W operation is USB 2.
Sensors
Six-axis motion sensing plus a replaceable camera, LED illuminator and microphone module.
Robotics
Six-axis motion sensing and a general-purpose interface for a future external robotics controller.
Construction
A durable polymer enclosure has continuous sides and an integrated rear, top and bottom. Common M3 screws secure the removable front for servicing.
