Glossary and specifications
Terms used throughout the operator manuals, plus the v1 hardware envelope. This is a product glossary — not a chip errata sheet.
Glossary
- B0rd OS
- The product firmware platform that drives the sign: apps, networking, notifications, and control paths.
- SoftAP
- Local Wi‑Fi access point advertised by the sign. Network nameB0rd-<suffix> (chip MAC or friendly-name slug); portal at
http://192.168.4.1/. - Settings
- Namespaced device preferences (
display.*,wifi.*,net.time.*,scene.timing.*,a11y.*) via SoftAP/api/settingsor USBsettings get|set|save. Dotted keys share the same names on both paths. Tables: Settings reference. - Mount orientation
- How the composed viewport is rotated before the HUB75 panel is driven — setting
display.orientation(0·90_cw·90_ccw·180). SoftAP Display →Display orientation; USBsettings set display.orientation …. SeeDisplay and idle clock. - Playlist / scene timing
- Automatic shared cycle between idle clock and launch countdown when countdown is the base preference — not a free-form media playlist. SeePlaylist and scene timing.
- Scene transition
- Curated whole-viewport wipe when the base scene changes:
cut,fade, and directionalslide_*/push_*. Slide covers; push displaces. See Scene transitions. - STA
- Station mode — the sign joins your home or lab network as a client for LAN access and outbound services.
- Idle clock
- Default calm mode: wall time with a soft motion underlay when nothing else owns the panel.
- Launch countdown
- Board mode showing upcoming missions with compact time-to-NET headers when wall time is known.
- NET
- No-Earlier-Than launch time shown on countdown cards.
- Notification
- Short title-and-body cue with optional timed dismiss. The base timeline continues underneath, and exit reveals its current presentation.
- USB control plane
- Line-oriented commands over USB for scripts and power users — preferred path when a cable is available.
- Host CLI (
b0rd) - Workstation tool that discovers signs on the LAN (
--channel http) and posts product Events over HTTP or MQTT. SeeHost CLI and MQTT Events. - MQTT Events
- Third Event channel: publish the same Event JSON to a broker; the sign subscribes when
mqtt.enabled. Equal to USB and HTTP Event vocabulary — not a separate command set. SeeMQTT Events. - HUB75
- Common LED matrix panel interface used by the product hardware target.
- App
- Something that puts content on the panel — background motion (for example plasma) or base chrome (for example launch countdown); more kinds may arrive later. Install means built into the OS image for that product — not a runtime download or app store on the sign. The shared platform keeps the idle clock and control plane; product apps such as plasma and launch countdown ship in the product build alongside it.
- Factory reset
- Clears Wi‑Fi and preferences back to SoftAP-first defaults (SoftAP More or USB, with explicit confirm).
.local- mDNS LAN name after home Wi‑Fi join — lowercase SoftAP identity (
b0rd-<slug|mac4>.local). Shown in SoftAP Status and USB health. Prefer USB or the numeric IP for scripts and Host CLI. SeeNetworking. - OTA
- Over-the-air OS update. Manifest check ships; apply is planned. Until enabled, operators flash from a trusted workstation. SeeUpdating the OS.
v1 hardware target
- 64×64 RGB matrix panel on a HUB75 interface
- Product module class: ESP32-S3 with a certified 64×64 matrix assembly
- Power: product-rated supply sized for continuous panel drive
- Control: USB serial channel; Wi‑Fi SoftAP and station
- Human setup: SoftAP portal; day-to-day: USB and LAN HTTP
Other boards and panel sizes are out of scope until certified for this OS release. Electrical and handling notes are inSafety and power.
