Extend two motor drivers, can directly drive two motors On-board power switch L293D: Motor power supply range: 4.5V~36V Control power supply range: 4.5V~9V Separate motor power supply and control power supply; in experiments, VIN and VM can be shorted by merging the short circuit blocks to supply power to the motor and control board at the same time Note: When inserting the ESP-12E module, please note that the antenna direction is the same as the direction of the expansion board. By utilizing the shorting module, power can be supplied to the control board and motor at the same time.  Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1*Motor Drive Expansion Board 1.Motor Driving Powerhouse: This motor driver expansion board combines the power of the ESP12 DEV KIT development board with the L293D dual motor driver, allowing you to directly control and drive two motors with ease. 2.Safety: With a wide motor power supply range of 4.5V to 36V and separate control power supply range of 4.5V to 9V, this lua module development board ensures safe and reliable operation for your motor control needs. The onboard power switch provides convenient control over the power supply. 3.Separate Power Supplies: The motor power supply and control power supply of this motor drive shield board can be separated, giving you flexibility in powering your motors and control board. By using the included shorting jumper, you can easily combine the power supplies for simultaneous motor driving and control. 4.Powerful Functionality: With the dual high-power H-bridge drive provided by the L293D, this motor shield driver board offers strong and efficient motor control capabilities. The ESP12E Dev Kit control ports (D1, D3 for motor A; D2, D4 for motor B) enable seamless integration with your projects. 5.Compact Size: With dimensions of 58.00x43.00x13.00mm (2.28x1.69x0.51 inches), this motor shield expansion board is compact and space-saving, making it suitable for various IoT and robotics applications where size constraints may be a concern.
