Mx1616 Motor Driver Datasheet [ UPDATED × SERIES ]

| Driver | Max Voltage | Max Current (cont) | Logic Inputs | Price (approx) | |--------|-------------|--------------------|--------------|----------------| | MX1616 | 7V | 1.0A | Yes (2-ch) | $0.80 | | L9110S | 12V | 0.8A | Yes | $0.70 | | DRV8837 | 11V | 1.8A | Yes | $1.20 | | TB6612 | 13.5V | 1.2A | Yes | $2.50 | | L298N | 46V | 2A | No (needs external logic) | $4.00 |

Verdict: MX1616 is best for low voltage (≤6V), low-power projects where cost and dropout voltage matter more than robustness.

Before wiring any circuit, you must understand the pinout. The Mx1616 is commonly available on a breakout board with a 16-pin configuration (screw terminals for motor/power and header pins for logic). Mx1616 Motor Driver Datasheet

Here is the standard pinout (viewed from the top, with the heat sink pad facing up):

| Pin # | Name | Type | Description | | :--- | :--- | :--- | :--- | | 1 | EN | Input | Enable driver (Low = driver ON; High = all outputs disabled) | | 2 | MS1 | Input | Microstep selection bit 1 (see truth table) | | 3 | MS2 | Input | Microstep selection bit 2 | | 4 | MS3 | Input | Microstep selection bit 3 (for 1/16 step) | | 5 | RST | Input | Reset active low – resets the translator to home position | | 6 | SLP | Input | Sleep mode (Low = sleep; High = normal operation) | | 7 | STP | Input | Step clock input (each rising edge advances the motor) | | 8 | DIR | Input | Direction control (High = CW, Low = CCW) | | 9 | VDD | Power | Logic supply voltage (3.3-5V) | | 10 | GND | Ground | Logic ground (must connect to system ground) | | 11 | VM | Power | Motor power supply (8-36V) | | 12 | PGND | Ground | Power ground (for motor return path) | | 13 | 1B | Output | Motor coil B – Phase 1 | | 14 | 2B | Output | Motor coil B – Phase 2 | | 15 | 2A | Output | Motor coil A – Phase 1 | | 16 | 1A | Output | Motor coil A – Phase 2 | | Driver | Max Voltage | Max Current

In the world of precision motion control, the choice of motor driver can make or break a project. Whether you are building a Computer Numerical Control (CNC) router, a 3D printer, a robotic arm, or an automated conveyor system, you need a reliable interface between your microcontroller (like an Arduino or Raspberry Pi) and your motors.

The Mx1616 Motor Driver has emerged as a popular choice in the mid-range stepper motor driver market. Known for its balance between power efficiency, microstepping accuracy, and thermal management, the Mx1616 is often compared to legacy drivers like the A4988 and the more modern TMC2209. Note: The "Mx1616" designation can sometimes refer to

This article serves as an exhaustive datasheet breakdown of the Mx1616. We will cover its pin configuration, electrical characteristics, wiring diagrams, programming logic, thermal specs, application use-cases, and troubleshooting tips.

Note: The "Mx1616" designation can sometimes refer to a family of drivers or a third-party variant of common chipsets. This guide assumes a generic high-performance bipolar stepper motor driver with 16-microstep capability and 1.6A current output per phase. Always verify with your specific manufacturer’s datasheet.
