SCHEDA DI ESPANSIONE MOTOR DRIVE L293D PER ESP8266 ESP12

1.Motor power (VM): 4.5 ~ 36V

2.Control power (VIN): 4.5V ~ 9V(10V MAX)

3.Provide the shorcut connector (short by VM and VIM), thus can use

4.May use common power source (4.5V~9V) by shorting VM and VIM

5.Controller Current (Iss):<=60mA (Vi=L), <=(Vi=H);

6.Motor working current (Io): <=1.2A;

7.Max power dissipation: 4W(T=90℃)；

8.Control signal input voltage:

2.3V<=VIH<=VIN (high)

-0.3V<=VIL<=1.5V (low)

9.Working temperature: -25℃ to +125℃ (non condensing)

10.Motor Drive: Dual high power H bridge

11.ESP-12E Dev Kit control port:

D1, D3 (motor A)

D2, D4 (motor B)

12.Finishing off the board there is even a nice big

ON/OFF power switch and LED power indication.
