The Motor Shield is built around the L293D quadruple high-current half-H driver, a reliable IC for driving motors. Designed for use with NodeMCU, this shield makes motor control simple and efficient by utilizing GPIO ports. It supports driving up to two motors, offering robust performance and ease of integration.

Note:

NodeMCU V2 board is not included

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 provided short-circuit sub module.

Pinout

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.

Package Includes

• 1 x Motor Shield for NodeMCU. (NodeMCU V2 board is not included)
