※ 아래 스펙을 참고하자.

• 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 provide the shorcut connector (short by VM and VIM), thus can use one power source (must be 4.5V~9V) to complete the drive and control for motor at a time.
• 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 Control Port: D1, D3 (A motor); D2, D4 (B motor)
• Expand two-way motor-driven, two-way direct drive motor
• Onboard power switch
