Features:

  • Dual Motor Support: Control two motors simultaneously with separate speed and direction settings.
  • Independent Power Supplies: Motor power supply (VM) and control power (VIN) can operate separately or be merged using the short-circuit submodule.
  • High-Performance Driver: Powered by a dual high-power H-bridge driver (L293D), suitable for demanding applications.
  • Versatile Power Range:
    • Motor power supply: 4.5V–36V
    • Control power supply: 4.5V–9V
  • Compact and Reliable: Withstands high temperatures (up to 125°C) and offers short-circuit protection for safe operation.

Specifications:

  • Motor Power Supply (VM): 4.5V–36V
  • Control Power Supply (VIN): 4.5V–9V (10V MAX)
  • Logic Operating Current (Iss): ≤60mA (Vi = L), ≤22mA (Vi = H)
  • Drive Current (Io): ≤1.2A
  • Maximum Power Dissipation: 4W (T = 90°C)
  • Input Signal Level:
    • High: 2.3V ≤ VIH ≤ VIN
    • Low: -0.3V ≤ VIL ≤ 1.5V
  • Working Temperature: -25°C to 125°C
  • Drive Type: Dual high-power H-bridge driver

Pinout:

Motor Shield Pin NodeMCU Pin GPIO Purpose
PWMA (Motor A) D1 GPIO 5 Speed Control
DIRA (Motor A) D3 GPIO 0 Direction Control
PWMB (Motor B) D2 GPIO 4 Speed Control
DIRB (Motor B) D4 GPIO 2 Direction Control

Notice:

  1. Power Configuration:
    • Motor and control power can operate independently.
    • Short the VIN and VM pins for combined power input (4.5V–9V).
  2. Module Alignment:
    • When connecting the ESP-12E module, ensure the antenna direction matches the expansion board orientation.
  3. Integrated Short Circuit Module:
    • Enables simultaneous control of both the board and motor for streamlined operation.
