Drive WS2812 / NeoPixel (and SK6812, WS2813/15, and clones) LEDs on the ESP32 using the I2S peripheral for rock-solid timing under load. Multiple parallel strips (one per I2S channel), multicore-safe, configurable color order, RGBW, brightness, HSV/gamma utilities, and both a C++ and a C API.
embedded-react engine — a tiny C99 UI engine for MCUs you drive with JSX (Flow B AOT, or Flow A via the QuickJS bridge). Backend-agnostic: you provide the framebuffer flush.
On-device SDK for connecting to Hubble's Terrestrial (Bluetooth Low Energy) and Satellite Networks, built on a modular architecture that ports across RTOSes and hardware.
WiFi lifecycle manager for ESP-IDF. Handles scanning, credential-based reconnection, and BLE provisioning as a single owned component — including disconnect recovery, multi-AP priority, time-window deadlines, retry-in-place provisioning and NVS-persisted credentials with LRU ranking. Other components observe state through an event interface and never touch esp_wifi directly.
AI-diagnosed crash reporting for ESP32. Captures fault registers, stack, and breadcrumbs before reset, resolves them to source via DWARF, and returns a plain-English root cause plus a ready-to-paste fix prompt for Cursor/Copilot. Free for up to 10 devices.
