6. Drive part of the work current Io: ≤1.2A
7. Maximum power dissipation: 4W (T = 90 ℃)
8. Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
9. Working temperature: -25 ℃ ~ + 125 ℃
10. Drive Type: Dual high-power H-bridge driver
11. ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
12. Expand two-way motor-driven, two-way direct drive motor
13. Onboard power switch
14. 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
