• Motor power supply (VM): 4.5V ~ 36V, can be powered separately 

• Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately 

• Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) while completing motor drive and control 

• Logic Operating current Iss: 60mA (Vi = L), 22mA (Vi = H) 

• Drive part of the work current Io: 1.2A 

• Maximum power dissipation: 4W (T = 90 ) 

• Control signal input level: High: 2.3V VIH VIN; Low: -0.3V VIL 1.5V 

• Working temperature: -25 ~ + 125 

• Drive Type: Dual high-power H-bridge driver 

• ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor) 

• Expand two-way motor-driven, two-way direct drive motor 

• Onboard power switch 

• Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power to the motor and the control board
