Unlock the mobility of your IoT projects with the ESP-12E Motor Shield. Built around the robust L293D driver chip, this expansion board is designed specifically for the NodeMCU ESP-12E Development Kit. It allows you to drive two DC motors directly while retaining access to all GPIO, SPI, and UART pins—perfect for building WiFi-controlled RC cars, smart robots, or home automation devices.

Key Features

• Seamless Compatibility: Directly mounts the ESP-12E Dev Kit (NodeMCU). Note: Please align the antenna direction correctly when mounting.
• Dual Motor Control: High-power L293D H-Bridge driver controls two DC motors simultaneously.
• Full Pin Access: Expands all ESP-12E functional pins (SPI, UART, GPIO, AI) and 3.3V power for easy sensor integration.
• Flexible Power Options: Supports separate power supplies for motors and logic, or a single power source via the onboard jumper (VIN/VM short).
• Onboard Power Switch: Conveniently turn your project on/off without unplugging cables.

Power Supply Guide

• Single Power Source: Short the VM and VIN pins with the jumper block. Input voltage must be 4.5V – 9V.
• Dual Power Source: Remove the jumper. Connect motor power (4.5V~36V) to VM and logic power (4.5V~9V) to VIN.
