Mx1616 Motor Driver Datasheet [upd] -

Most MX1616 modules follow a standard 8-pin or SOP16 interface for control and power: + (VM/VCC): External motor power supply (2V–10V). - (GND): Common ground for both power and logic signals. Control Inputs: IN1 / IN2: Controls Motor A direction and speed (PWM). IN3 / IN4: Controls Motor B direction and speed (PWM). Motor Outputs:

| Pin # | Name | Function | | :--- | :--- | :--- | | 1 | VM | Motor power supply (4.5V – 13.5V) | | 2, 9 | AO1, BO1 | Output A1 / Output B1 | | 3, 8 | AO2, BO2 | Output A2 / Output B2 | | 4 | PGND | Power ground for motors | | 5 | VCC | Logic supply (2.7V – 5.5V) | | 6 | STBY | Standby (High = Active; Low = Standby) | | 7, 15 | AIN1, BIN1 | Input 1 for Channel A / Channel B | | 10, 14 | AIN2, BIN2 | Input 2 for Channel A / Channel B | | 11 | PWMA | PWM input for Channel A (speed control) | | 12 | GND | Logic ground | | 13 | PWMB | PWM input for Channel B (speed control) | | 16 | VREF | Reference voltage (usually tied to VCC) | Mx1616 Motor Driver Datasheet

One evening after the festival, Jun sat on the lab floor amid reels of wire and a half-made control board. "Why Mx1616?" Jun asked. Most MX1616 modules follow a standard 8-pin or

, which significantly reduces power loss compared to transistor-based drivers. IN3 / IN4: Controls Motor B direction and speed (PWM)
