Specification:
Origin: Mainland China
Type: Module
Condition: New
Model Number: Haptic Motor Controller
color: blue
Embedded processor:
Vin: Powers the board and gives it the same power level as a microcontroller, e.g. 5V micro (eg for Arduino), uses 5V
GND: power and logic
Common ground for I2C pins:
SCL: I2C clock pin, connected to the I2C clock line of the microcontroller. This pin can be used with 3V or 5V logic, there is a 10K pull-up resistor on this pin
SDA: I2C data pin, connected to the I2C data line of the microcontroller. This pin can be used with 3V or 5V logic circuits, this pin 10K pull-up on IN/TRIG: This is a general purpose pin and can be used for several purposes. One use is to read the analog audio input to control audio to haptic codes, and the other is to "trigger" effects instead of sending I2C commands.
Size: 18x15x3 (mm)/0.71x0.59x0.12inch

1. The DRV2605 is a nice little motor driver. It is not designed to control stepper motors or DC motors, but is specifically designed to control haptic motors - buzzer and vibration motors.
2. The chip is controlled by I2C. After initialization, multiple "string" effects can be stringed into the chip memory, and then triggered to drive continuously. Built-in effects are far better than "on" and "off" and will make your tactile sense even better.

Features:
1. Control haptic motor: This product is specially used to control haptic motor. It is usually only necessary to turn these types of motors on and off.
When driving a vibrating motor, this drive has several effects. For example, up and down vibration levels, different buzzer levels, and even vibration will follow the music/audio input.
2. Built-in "strings" of multiple effects: After the product is initialized, the "strings" of multiple effects can be stringed together in the chip memory, and then triggered for continuous actuation,
This will give you a better feel for how your tactile projection works.
3. With I2C pins: This product has multiple I2C pins that can be used for 3V or 5V logic, and there is a 10K pull-up resistor on this pin.
4. With IN/TRIG: This product has an IN/TRIG general-purpose pin that can be used for different purposes, including reading analog audio to control audio to produce tactile codes, and "trigger" effects.
5. Using a Vin processor: This product has a Vin processor that can power the board and give it the same logic level as the microcontroller.

Note:
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.
