ESP8266 Development Board L293D Motor Drive Shield Expansion Board Based On ESP-12E For NodeMCU

ESP8266 Development Board L293D Motor Drive Shield Expansion Board Based On ESP-12E For NodeMCU
 
Features:
- ESP12 DEV KIT development board expansion module;
- Lead out all function pins of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power supply interface;
- Extended two-way motor drive, can directly drive two-way motor;
- Onboard power supply switch;
- L293D;
- Motor power supply range: 4.5V~36V;
- Control power supply range: 4.5V~9V;
- Motor power supply and control power supply are separated; in experiments, short circuit block can be combined to short-circuit VIN and VM, and power is supplied to motor and control board at the same time.

Specifications:
- Power supply input:
* Motor power supply (VM): 4.5V ~ 36V, can be powered separately;
* Control power supply (VIN): 4.5V ~ 9V (10V max.), can be powered separately;
* Module provides short-circuit (short-circuit VM and VIN), you can easily use one power supply (must be 4.5V ~ 9V) at the same time complete the drive and control of motor;
- Logic working current lss: ≤ 60mA (Vi=L), ≤ 22mA (Vi=H);
- Drive part working current Io: ≤ 1.2A;
- Maximum power dissipation: 4W (T=90℃)
- Control signal input level: high level: 2.3V≤ VIH≤ VIN; low level: -0.3V≤ VIL≤ 1.5V
- Working temperature: -25℃ to 125℃
- Driving mode: dual high-power H-bridge driver
- ESP12E Dev Kit control ports: D1, D3 (motor A); D2, D4 (motor B)
- Module weight: about 20g

Attention:
- When inserting ESP-12E module, please note that the direction of antenna is consistent with the direction of expansion board;
- Short circuit module can be used to supply power to control board and motor at the same time.

Package Included:
- 1 x Expansion Board
