Assembly

I currently don't have wiring diagram but it is quite simple.

Accessory 12V -> Step down -> 5V for ESP32 Accessory 12V -> Cruise Button (on/off) -> Cytron Input Cytron 5V (goldpins) -> ESP32 (pin 16 - detecting button pressed) CYTRON_M2A_CLUTCH_ON (goldpins) -> ESP32 (pin 17) CYTRON_M1A_SPEED_UP (goldpins) -> ESP32 (pin 18) CYTRON_M1B_SPEED_DOWN (goldpins) -> ESP32 (pin 19) Common ground for all elements

Hardware Components

ESP32 Board

I'm using typical ESP32 development board.

ELM327

I'm using V-LINK ELM327 connector

Cytron - MDD3A

The Cytron MDD3A motor controller can control 2 DC motors or 1 stepper motor. The continuous current per level is 3 A (5 A high). The supply voltage is from 4 V to 16 V. The controller works with a logical voltage of 1.8 V, 3.3 V, 5 V and 12 V (PWM and DIR), thanks to which it is possible to control using a microcontroller such as Arduino or Raspberry.
