Bacopa: 6-Channel LED Driver / Carrier for Buce

Bacopa Module Appearance

The Appearance of Bacopa Module

Overview

Bacopa is the LED driver/carrier board for the Buce 6-channel WiFi LED controller (BLC06). Engineered with premium components and careful design, Bacopa delivers 700 mA constant-current output per channel, capable of driving a total of up to 162 W of LEDs (approximately 54 × 3 W high-power LED beads).

Under the control of the Buce LED controller’s 6-channel phase-shifted interleaved output, 12-bit duty cycle resolution, and up to 19.5 kHz ultra-high-frequency PWM dimming signal, completely flicker-free smooth dimming is achieved while fully eliminating audible noise from inductors and ceramic capacitors.

BLM06 integrates reverse-polarity protection circuitry and a current sensor. In conjunction with the Buce controller, it provides not only up to 130 W constant-current power output but also reverse-polarity, over-temperature, and over-current protection. Combined with the companion controller’s multi-segment programmable dimming, astronomical algorithm-based sunrise/sunset simulation, moonlight simulation, adaptive thermal management, and LED power monitoring, it serves as the ideal core hardware for premium aquarium luminaires, indoor agriculture/horticultural lighting, and smart lighting applications.
