⚠️ Note: Unlike the TB6612 or L298N, the MX1616 does not have overcurrent protection. External current limiting is recommended for inductive loads.
Pinout Breakdown
The Mx1616 module typically features a standard 2.54mm pitch pin header layout. The datasheet identifies the following pins: MX1616 Dual Brushed DC Motor Driver IC –
Power Pins:
- VM / VCC: Motor Power Supply input (2V–10V).
- GND: Ground (Common ground for motor power and logic).
Control Inputs (Logic Side):
- IN1 & IN2: Control inputs for Motor A.
- IN3 & IN4: Control inputs for Motor B.
Output Pins (Motor Side):
- OUT1 & OUT2: Output terminals for Motor A.
- OUT3 & OUT4: Output terminals for Motor B.
Special Function Pins:
- STBY (Standby): This pin controls the sleep mode.
- Low (0): The chip enters sleep mode; motors stop, and power consumption drops to near zero.
- High (1): The chip is active.
- Tip: If you do not need the sleep function, connect this pin directly to 5V or your logic voltage source.
What makes the Mx1616 stand out?
- High Resolution: Supports up to 1/16 microstepping, which reduces resonance and vibration at low speeds.
- Low Power Dissipation: With a typical RDS(on) of 0.45Ω, it runs cooler than older drivers like the A4988.
- Decay Modes: Features both slow and mixed decay modes, allowing fine-tuning for different motor inductances.
