AtlasCube

Audio

Internet radio — MP3, AAC, FLAC
HLS (.m3u8) live streams
ICY metadata display
Playlist — up to 512 stations
Station logos — artwork per station, looked up on Radio Browser or uploaded from your own file, converted in the browser and stored on the SD card
Podcasts — an episode plays as a finite stream with its title on screen and resumes where you left off; the Android app is the catalog
SD music player — local files with ID3 tags, shuffle / repeat
Network Music — plays MP3s straight off a NAS, a spare box with nginx on it, or any other HTTP server the radio can reach, browsing its folders on the device or in the web player, with the track length read from the file itself. Needs a server that answers directory requests with JSON over plain http:// — the setup page has a complete nginx config to paste
10-band parametric EQ
Mono downmix for single-speaker builds
Bluetooth A2DP sink + HFP hands-free
Codecs: LDAC, aptX HD, aptX LL, aptX, SBC, AAC
External QCC5125 module, BT 5.1
74HC157D I2S mux — hardware source switching via GPIO

Display & UI

LVGL GUI on ILI9341 320×240, ST7789V 320×240, ST7796U 480×320, ILI9488 480×320 TFT, CO5300 240×296 AMOLED, or SSD1322 256×64 mono OLED — selected at compile time
Clock, radio, playlist, EQ, settings screens
Audio VU meter — real-time FFT spectrum on the radio screen
Analog needle VU — two independent L/R needle meters overlaid on the wallpaper, so meter faces can be part of the background image
Stereo bar VU — two L/R bars with optional peak-hold, placed and coloured per screen
Dark and light themes
Rotary encoder + capacitive touch (CST816D or FT6336U) or resistive touch (XPT2046)
Push-buttons with configurable actions — up to ten buttons, each wired straight to a GPIO and GND with no extra parts. Short and long press are separate actions, so ten buttons cover twenty commands: playback, volume, mute, source switching, jumping to a screen, or menu navigation for a build with no rotary encoder at all. Pick the pins on the setup page, pick the actions in the web UI
180° flip, colour inversion and independent touch orientation — all live from the web UI, for panels mounted upside-down or wired differently
Swipe gestures to switch screens; swipe-up opens settings / playlist
Tap-to-show on-screen controls overlay (play/pause, vol±, prev/next)
Visual widget layout editor with grouped controls and semantic previews
Theme-aware, adjustable background plates keep labels and station information readable over wallpapers
Wallpaper from SD or an internet JPEG URL — a different one per screen, presets, scheduled refresh, save to SD, and adjustable dimming
Online wallpaper gallery — browse artwork matching your panel resolution and install it to the device without leaving the layout editor
Custom boot splash logo from SD
Photo slideshow from SD
Screensavers — clock hands, starfield, fireworks, plasma, Game of Life, blank, Dim, or Dashboard

Weather

Optional current temperature and conditions on the home screen
Weather Icons with day/night condition variants
Open-Meteo works without an API key
OpenWeatherMap available as an alternative provider
Coordinates and refresh interval configured from the web UI

Events & notifications

Birthdays, namedays, reminders
Recurring: daily / weekly / monthly / yearly
Phone calendar mirror — the Android app pushes your upcoming entries to the device, read-only
Fullscreen alert + buzzer melody
Playback schedule — start radio or SD music with an optional stop time
Voice notifications — play a recorded clip from SD at a set time
Programmable notification tunes

Connectivity

WiFi with captive-portal setup (AP mode), or type the password on the device itself
HTTP + WebSocket server on-device
Web UI served from SPIFFS — no cloud
mDNS — reachable at <hostname>.local, so the app and your browser find it without an IP
NTP with configurable timezone
MQTT — radio control + up to 6 widgets (toggle / slider / label) on a dedicated on-device screen
OTA firmware update from the web UI — dual-slot with rollback + firmware backup (16 MB builds)
Automatic updates — the device checks for a new release at boot and, after an on-screen confirmation, installs new firmware and refreshes the web UI by itself

Remote control

Android app — available on Google Play: playback, playlist, events, equalizer, layout editor and a podcast browser
Voice commands from the phone — English, Polish, Czech, German, French, Hungarian and Hindi
Hardware pilot over ESP-NOW — a battery-powered remote that never joins the WiFi, so a button press acts immediately instead of waiting for a connection; it can browse and play the SD card and read the radio's settings and diagnostics
MQTT commands from any automation system
One documented command set behind all of them — web UI, app, pilot and MQTT speak the same protocol

Setup & maintenance

Runtime pin map — every GPIO is configured on the device's own setup page and stored in flash, so one firmware binary drives any wiring, no rebuild
Diagnostics — memory and PSRAM use, chip temperature, firmware and web-UI versions, MQTT broker state; on screen and as a copyable report in the web UI
One-file backup — export settings, theme, events, MQTT config, layout and station list as a single JSON and restore it later; no SD card needed
SD file manager in the browser — browse, upload, rename, move and delete, with inline preview of display images
SPIFFS ⇄ SD copy tool for backing the device up to the card
Built-in text editor for the configuration and web files

Dashboard screensaver

Ambient display polling any JSON HTTP/HTTPS endpoint and rendering a single value
Configurable title, URL, JSON path, suffix, and poll interval
HTTPS out of the box via ESP-IDF certificate bundle
Ships with NBP USD/PLN rate; point it at weather, crypto, home automation, GitHub stats, …

Coming soon

Enclosure — 3D-printed case in design; runs on the custom AtlasCube PCB as well as bare dev boards
Web melody editor — in-browser tool for composing buzzer tunes
Infrared remote — a €1 receiver on one GPIO, taught the keys of any spare TV remote; the keys map onto the same action list the push-buttons already use
