Description
The BTS7960 43A H-Bridge Motor Driver Module is an exceptionally powerful motor controller built for high-demand robotics applications, replacing weaker drivers like the L298N when extreme torque or heavy chassis movement is required.
If your DC geared motor draws a lot of current (especially under load or when stalled), the BTS7960 module is exactly what you need. While the L298N maxes out at 2A per channel, this module is rated for a massive 43 Amps peak current.
Product Description
-
Architecture: It utilizes two BTS7960 high-current half-bridge chips (forming a full H-bridge together) combined with an integrated 74AHC244 buffer chip that protects your STM32 from high-voltage spikes and static discharge.
-
Heat Management: Features a very thick, heavy-duty aluminum heatsink bolted to the back of the PCB to safely dissipate the heat generated during high-current switching.
-
Logic Isolation: It completely isolates your STM32 microcontroller from the noisy and dangerous motor power supply.
Key Specifications
-
Motor Supply Voltage: 6V to 27V DC.
-
Maximum Current: 43A (Peak). Continuous current heavily depends on cooling but easily handles 10A-15A comfortably.
-
Logic Control Voltage: 3.3V to 5V (Fully compatible with STM32 GPIO and PWM pins).
-
PWM Frequency: Up to 25 kHz, which is outside the range of human hearing, ensuring your motors don’t “whine” when PWM dimming/speed control is applied.
-
Built-in Protection: Over-voltage, under-voltage, over-temperature, and short-circuit protection are natively built into the chips.
