ESP8266 NodeMCU WiFi Expansion Board with L293D Motor Driver
L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.
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. Logic Operating Current: ≤60mA (Vi = L), ≤22mA (Vi = H)
4. Drive part of the Work Current Io: ≤1.2A
5. Maximum Power Dissipation: 4W (T = 90 ℃)
6. Control Signal Input Level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
7. Working Temperature: -25 ℃ ~ + 125 ℃
8. Drive Type: Dual high-power H-bridge driver
9. ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
10. Expand two-way motor-driven, two-way direct-drive motor
11. Onboard power switch
