NodeMCU Motor Driver Shield can be used to run 2 DC Motors simultaneously and also acts as an expansion board for NodeMCU Devkit 1.0.
This shield board is driven by the large power full-bridge chip L293DD, which can directly drive 2-channels DC motors or one-channel stepper motor. The current can be up to 1.2A.
The shield board has four ports which are used as PWMA(motor A), PWMB (motor B), DA (direction of motor A), and DB (direction of motor B), respectively.
In addition, this shield board has many pins, such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, and EN, thus can conveniently connect all kinds of sensors (e.g., temperature and humidy, buzzer, light, relay sensor, etc.). The board is developed by the humanized design with a power switch, and thus user can control the on-off of power conveniently.This motor shield board can be used to control directly the smart car.
Motor power (VM): 4.5~36V, can be powered separately
Control power (VIN): 4.5V~9V(10V MAX), can be powered separately
Logic working current (Iss) 60mA
Driven working current (Io): 1.2A
Control signal input voltage: High (above 2.3V), Low(between 0.3 and 1.5V)
Ports: D1, D3 (Motor A); D2, D4 (Motor B)
