04 / Pocket field kit
Ghostwire
A Cardputer ADV companion for local radio observation and authorised network scouting.
THE QUESTION
How much useful field context can fit in a pocket tool?
THE APPROACH
Ghostwire brings Wi-Fi, BLE, mesh, network, and local evidence workflows to the M5Stack Cardputer ADV. Its on-screen Familiar gives the device a distinctive way to surface changes during exploration.
DESIGN DETAILS
- SD-backed records can be moved to a workstation for later review.
- A separate Unit PoE-P4 companion provides wired capability.
- The repository documents authorised use, supported hardware, and release checks.
