Product Description:

• Name: nodemcu motor shield
• Using ESP-12 DEVELOPMENT KIT Development Shield Module
• Extend output ports for DEVKIT of ESP-12: SPI, UART, GPIO, AI and 3.3V power interface
• Extend 2-way motor, then directly drive 2-way motor
• Design a power switch
• Voltage for motor: 4.5V-36V
• Voltage for ESP control board: 4.5V-9V
• Conduit cihip: L293D

Power supply:

• ~ Motor power (VM): 4.5V ~ 36V, can be a separate power supply;
• ~ Control power (VIN): 4.5V ~ 9V (10VMAX), can be operated separately;
• ~ The Module provides a sub-circuit (short the VM and the VIN), you can easily use power (must 4.5V ~ 9V) simultaneously drive and control the motor;
• Logic operating current Iss: 60mA (Vi = L), 22mA (Vi = H);
• Drive part of the working current Io: 1.2A;
• Maximum power dissipation: 4W (T = 90)
• Control signal input level: high: 2.3VVIHVIN; Low: -0.3VVIL1.5V
• Working temperature: -25 ~ + 125
• Drive type: high power dual h-bridge driver
• ESP12E Development Kit Control Port: D1, D3 (Engine A); D2, D4 (engine B)
• Module Weight: about 20g
