Description:
The NodeMCU Motor Shield Board L293D is designed for ESP-12E development kits (NodeMCU). This motor shield enables you to easily control and drive 2-way motors with the L293D high-power dual H-bridge driver. It extends the capabilities of your NodeMCU by offering additional I/O ports like SPI, UART, GPIO, AI, and 3.3V power interfaces. The shield supports a wide motor voltage range of 4.5V-36V and can be powered separately from the ESP board. It includes a built-in power switch and is perfect for applications involving motor control, automation, and robotics.
FAQ:
-
What voltage range can this motor shield support for motors?
- The shield supports motor voltages ranging from 4.5V to 36V.
-
Can I use a single power source for both motor and control?
- Yes, the shield includes a sub-circuit that allows you to power both the motor and the ESP control board from a single power supply (4.5V ~ 9V).
-
What current does the motor shield draw during operation?
- The logic operating current is 60mA (Vi = L) and 22mA (Vi = H), while the drive part works with a current of 1.2A.
-
Can I use this shield with other ESP modules besides ESP-12E?
- This shield is specifically designed for the ESP-12E (NodeMCU), but you can explore compatibility with other ESP modules depending on the pin configuration.
-
What is the maximum temperature at which the module can operate?
- The module can operate in a temperature range from -25°C to +125°C.
