Start here01
The basics
The keys, the Launcher, the Status Bar and what happens the first time you switch the device on.
User guide
How to use each App on the Cardputer: the keys, what the screens show, and what is written to the SD card.
This guide says what the firmware does today and nothing else. Start with the basics (the keys, the Launcher, the first start), then read the page of any App. It describes the latest release; the numbers and key names come from the firmware's own source.
The mesh messenger is planned, not built. The LoRa Scanner listens to Meshtastic traffic and shows it, but the device sends nothing yet: that is the next milestone and waits for a second node to test with.

LoRa Scanner02
LoRa Scanner
Listen to the radio: every packet it hears, a survey of signal strength from 863 to 870 MHz, and captures for Wireshark. It only listens.
GNSS03
GNSS
Where you are and which satellites you can see, from the Cap's receiver, with Tracks saved to the SD card as GPX.
Gemini04
Gemini
Browse Geminispace: follow links, go back, bookmark pages and keep them on the SD card to read offline.
IRC05
IRC
Chat on an IRC server from the keyboard, with a connection that outlives the App and daily logs on the SD card.
Wi-Fi tools06
Wi-Fi tools
See the networks around you, which Wi-Fi channels are busy, and follow one network's signal as you move.
Notes07
Notes
Plain text notes on the SD card, with no save key: the editor saves for you, and a power cut never costs the note.
Storage08
Storage
Browse the SD card: copy, move, rename and delete with a clipboard, and open a file by its type.
System09
System
What the device is doing right now: load, tasks, memory, network traffic, battery and temperature. Live, and read-only.
Settings10
Settings
The device's names, region, screen, sound, GNSS and Wi-Fi, and where firmware updates are found.
Firmware11
Updates
How the device updates itself from the project's releases, from the SD card or from a PC, and how it protects itself when an update goes wrong.
