NodeMCU Motor shield for ESP-12E

This is the first motor shield for ESP8266 based on ESP-12E. It is very convenientand cheap to diy a WiFi RC smart car.

Feature :

• 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
