Driver Datasheet - Mx1616 Motor

| Document Number: DS-MX1616-0124

Pulse Width Modulation (PWM) is used to control the motor's speed. This is done by applying a high-frequency PWM signal (typically 1-20 kHz) directly to either the or IN2 control pin.

The motor driver interprets standard logic levels (High/Low) to dictate motor direction and speed. Pulse Width Modulation (PWM) can be applied to the input pins to vary the speed.

Always double-check the specific datasheet provided by your module's supplier, as clone variations of the MX1616 chip may have slight differences in peak voltage tolerance. Pulse Width Modulation (PWM) can be applied to

Verify that the motor supply is connected to the proper VM pin and that GND is shared with the Arduino.

| Variant | Continuous (per ch) | Peak | VM Range | Standby Current | Notes | |---------|-------------------|------|----------|-----------------|-------| | MX1616H | 1.3 A (two‑ch) / 1.6 A (single) | 3.0 A | 2.0–8.6 V | <0.1 µA | Most widely available, includes TSD, 4 kV HBM | | MX1616L | 1.2 A (two‑ch) / 1.6 A (single) | 2.5 A | 2.0–8.0 V | <0.1 µA | Slightly lower peak; RDS(on) = 0.32 Ω | | MX1616RX2 | 1.7 A (two‑ch) | 2.5 A | 2.5–8.0 V | – | No over‑current protection; only TSD | | MX1616S | 1.3 A | 3.0 A | 2.0–7.5 V | – | |

The Mx1616 is a compact, dual-channel DC motor driver module popular among hobbyists and robotics engineers. While the physical module is small—often no larger than a postage stamp—it packs a significant punch for its size, capable of driving two DC motors or a single stepper motor.

The Mx1616 motor driver is a versatile and efficient solution for a wide range of motor control applications. Its compact package, high current output, and protection features make it an ideal choice for robotics, industrial automation, and consumer electronics.

PWM speed control is just as easy: replace digitalWrite with analogWrite on the input that sets the direction. For example, analogWrite(ina1, 128); digitalWrite(inb1, LOW); drives motor A at ~50% duty forward.
