Product details

Features

• ESP12 DEV KIT development board expansion module;
• Lead out all function pins of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power interface;
• Extend the two-way motor drive, which can directly drive the two-way motor;
• Onboard power switch;
• Motor power supply range: 4.5V~36V;
• Control power supply range: 4.5V~9V;
• Motor power supply and control power supply are separated; in the experiment, the short-circuit block can be combined to short-circuit VIN and VM, and power the motor and control board at the same time.

Power input

•  Motor power supply (VM): 4.5V～36V, can be powered separately;
• Control power supply (VIN): 4.5V～9V (10VMAX), can be powered separately;
•  The module provides a short circuit (short-circuit VM and VIN), you can easily use a power supply (must be 4.5V ~ 9V) at the same time to complete the drive and control of the motor;
