The Gicren Booster-B36V2A5 is a dual H-bridge brushed DC motor controller built around 2×4 N-channel MOSFETs with very low on-resistance (RDS(on) <1.6 mΩ). It can drive two motors independently or be configured for a single higher-current motor, and also supports driving high-power LEDs.

The controller communicates via RS485 or I²C through a shared connector and register map, allowing seamless switching between interfaces. With 18 built-in control modes and comprehensive hardware protection, it suits a wide range of motor control applications.

Key Features

• Dual H-Bridge – Drive two brushed DC motors independently, or combine channels for a single motor
• Wide Voltage Range – 6–36 V DC input
• High Current Capacity – 2×5 A continuous (D-Sub limited) or 1×10 A; MOSFETs rated for 2×15 A / 1×20 A
• Comprehensive Protection – Under-voltage, over-voltage, over-temperature, over-current, runaway, and reverse-polarity protection (hardware comparator for fast over-current response)
• 18 Control Modes – Configurable for various motor control scenarios
• RS485 & I²C – Both interfaces share a common register map; RS485 supports auto baud detection (1200–115200 bps)
