Description
ESP-12E motor drive expansion board
- Based on the first motor-driven expansion board ESP-12E development.
- ESP12 DEV KIT development board expansion module;
- lead ESP12 DEV KIT All-function pins: SPI, UART, GPIO, AI and 3.3V power connector;
- expand two-way motor-driven, two-way direct drive motor;
- onboard power switch;
- L293D
- Motor power range: 4.5V ~ 36V;
- Control power range: 4.5V ~ 9V;
- Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power supply to the motor and the control board.
Technical Specifications
Power input:
- Motor Power (VM): 4.5V ~ 36V, can be a separate power supply.
- Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately.
- Module provides short-circuit sub (short the VM and VIN), you can easily use one 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 work current Io: ≤1.2A.
- Maximum power dissipation: 4W (T = 90)
- Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
- Working temperature: -25 ~ + 125
- Drive Type: Dual high-power H-bridge driver
- ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
Product instructions
- Please refer to product catalog to check if product is suitable for tough grinding (turmeric, masala, etc.)
- Please allow the motor to cool for some time between product uses. Most Mixer Grinders come with overload protection which automatically turns off the motor in case of overheating.
- Burning smell during first few usages is normal due to varnish coating on motor and will stop after few usage cycles.
Suitable for ESP8266 NodeMCU lua CP2102 wifi internet development board.
