##wiring ESP DRV 8830 GPIO 4 | SDA GPIO 5 | SCL VIN | Vcc GND | Gnd
- connect to the ESP only with I2C pulled up with 3.3v.
- Motor (+) and OUT1, motor (-) and OUT2
- A 1 nF (102) ceramic capacitor between + and - of the motor
- A resistance of 0.2 Ω between ISENSE and GND of the DRV 8830
- 0.1 μF (104) ceramic capacitor between VCC and GND of the DRV 8830
- A 10 kΩ resistor between SDA and 3.3 v
- A 10 kΩ resistor between SCL and 3.3 v
- 5 V output such as USB serial and VIN of ESP - WROOM - 02 board
