Connect the ESP32's 5V Output pin to the 5V input of the L298N driver board (red wire)
Connect a ground from the ESP32 to the L298N driver board (black wire)
Connect the L298N driver board's 5V and 12V terminals together (red jumper wire)
Make sure the L298N's jumpers are in place (small blue wires on board)
Connect the ESP32's GPIO25 to IN1 on the L298N driver board (yellow wire)
Connect the ESP32's GPIO26 to IN2 on the L298N driver board (blue wire)
Connect the DC motor to channel 1 on the L298N driver board.
- Note: polarity does not matter here
- You may add an external button off GPIO 13 on the ESP32; this will enable and disable winding

Important

This wiring diagram assumes you've purchased an I2C 4-wire OLED (SSD1306 driver compatible). Complex LCDs are currently not supported.

Connect the ESP32's 5V output pin to the 5V input of the L298N driver board (red wire)
Connect the ESP32's 5V output pin to the VCC input pin on your OLED screen
Connect a ground wire from the ESP32 to the L298N driver board (black wire)
Connect a ground wire from the ESP32 to the OLED screen's GRND pin
Connect a wire from the ESP32's D22 pin to the OLED screen's SCL pin
Connect a wire from the ESP32's D21 pin to the OLED screen's SDA pin
Connect the L298N driver board's 5V and 12V terminals together (red jumper wire)
Make sure the L298N's jumpers are in place (small blue wires on board)
Connect the ESP32's GPIO25 to IN1 on the L298N driver board (yellow wire)
Connect the ESP32's GPIO26 to IN2 on the L298N driver board (blue wire)
Connect the DC motor to channel 1 on the L298N driver board.
