บอร์ดขับมอเตอร์ L293D แบบ Shield สำหรับ NodeMCU V2 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.
คุณสมบัติ Motor Driver (L293D) Shield for NodeMCU V2 :
- 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: 2.3VVIHVIN; Low: -0.3VVIL1.5V
- 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
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.
