Hyperk is a minimalist, high-performance uni-platform WiFi/Ethernet LED driver for ESP8266, ESP32 (S2, S3, C2, C3, C5, C6), Raspberry Pi Pico W (RP2040, RP2350). Designed as a lightweight and streamlined component that avoids unnecessary complexity, it delivers low‑latency performance and integrates smoothly with platforms such as HyperHDR, while offering essential home‑automation capabilities through a clean, modern codebase.
The firmware can be flashed directly from your browser: hyperk.hyperhdr.org
Tip
Once installed, you can also perform OTA updates directly through the local Web GUI.
