Motor Driver Shield Board L293D For NodeMCU V2

AED 15.00



The shield is based on the L293D quadruple high-current half-H drivers typically used to drive motors. the shield utilizes some of the GPIO ports to control the motor. The motor shield supports two motors.
Motor power supply (VM): 4.5V ~ 36V, can be powered separately
Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately
The 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 = 90C)
Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
Working temperature: -25C - 125C
Drive Type: Dual high-power H-bridge driver
Pinout of the Board:
Motor Shield NodeMCU DevKit GPIO Purpose
D1 PWMA (Motor A) D1 5 Speed
D3 DIRA (Motor A) D3 0 Direction
D2 PWMA (Motor B) D2 4 Speed
D4 DIRB (Motor B) D4 2 Direction

Motor power, control power separation; In the experiment, by short-circuiting block, the merger, the VIN and VM short, while the power to the motor and the control board
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 the board and motor.
