Power control (VIN): 4.5V ~ 9V (10VMAX), can be powered separately. The module provides a short circuit (connecting VM and VIN), you can easily use a single supply (must be 4.5V ~ 9V) while completing the driving and motor control.

Logic operating current Iss: ≤60mA (Vi = L), ≤22mA (Vi = H). Operating current of the driving part Io: ≤1.2A.

Maximum power dissipation: 4W (T = 90°C). Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V.

Operating temperature: -25°C ~ + 125°C. Driving type: Dual high-power H-bridge driver.

ESP12E Dev Kit Control ports: D1, D3 (Motor A); D2, D4 (Motor B). Two-way motor drive expansion, direct two-way motor drive.

Built-in power switch. Separation of motor and control power; During experiments, with the short-circuit block of merging, VIN and VM are short-circuited, while power is supplied to the motor and the control board.
