Power input:

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