L293D Motor Driver Shield for NodeMCU ESP8266 This is the first motor shield for ESP8266 based on ESP-12E. It is very convenient and cheap to diy a WiFi RC smart car. Feature : 1. Motor power supply (VM): 4.5V ~ 36V, can be powered separately 2. Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately 3. 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. 4. Logic operating current Iss: ≤60mA (Vi = L), ≤22mA (Vi = H) 5. Drive part of the work current Io: ≤1.2A 6. Maximum power dissipation: 4W (T = 90 ℃) 7. Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V 8. Working temperature: -25 ℃ ~ 125 ℃ 9. Drive Type: Dual high-power H-bridge driver 10. ESP12E Dev Kit Control Ports: D1, D3 (A motor); D2, D4 (B motor) 11. Expand two-way motor-driven, two-way direct drive motor 12. Onboard power switch 13. 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 Notice: When inserted into the ESP-12E module, please note the direction consistent with an expansion board antenna. The use of short modules that can simultaneously control board and motor. commonly used in conjunction with NodeMCU ESP8266 V2 CH9102 LUA Wifi based ESP8266-12E NodeMCU ESP8266 V2 CP2102 LUA based ESP8266-12E NodeMCU ESP8266 V2 CP2102 LUA Wifi based ESP8266-12F/N How to connect the device, tutorial, use ESP8266 Motor Driver L293D Shield for NodeMCU V2 Motor Driver Board for ESP8266 NodeMCU V2 1.
