Pocket specifications

Size
84 × 34 × 117.1 mm.
Compute
The STM32H743 application controller works independently. The modular compute bay can house a Raspberry Pi Zero 2 W, Compute Module 5 or a custom PCB.
Storage
Application-controller microSD logging, plus replaceable microSD for the optional Pi.
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 without the Pi.
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 status, NFC and two external USB-C ports. 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, light and microphone module.
Construction
The screw-fastened case opens for repair. Cells, boards, controls, USB harnesses and exterior inserts can be replaced independently, with no structural glue.
