Description

LedBox V2 is a small module for controlling 3 and 4-wire addressable LED strips such as WS2812, SK6812, etc. It is based on a powerful ESP32 microcontroller with integrated Wi-Fi, dual-mode Bluetooth, and enough processing power to perform real-time digital signal processing.

The module has a dedicated step-down converter, which allows to seamlessly use both 5V and 12V strips. Moreover, it contains a digital MEMS microphone, side button, 32kHz IR receiver, 10A safety resettable fuse, 1000µF buffer capacitor, 3.3V/5V level converter for both Data and Clock lines, together with an impedance matching resistor. These features ensure maximum functionality, safety, and led strip compatibility, all in a small (54x32x18mm) 3D printable enclosure.

Writing your own firmware is option which unlocks limitless possibilities, but to avoid reinventing the wheel, the module is by default fully compatible with WLED and Sound Reactive WLED firmware for Wi-Fi control.
