*x_axis* and *y_axis* fields capture analog input from a joystick, determining direction and speed.
*nav_bttn* represents a joystick push-button.

*motor1_rpm_pwm* to *motor4_rpm_pwm* provide individual PWM signals to four DC motors.
This enables fine-grained speed control, supports differential drive configurations, and even allows for maneuvering in multi-directional platforms like omni-wheel robots.
Why Use __attribute((packed))?
Why use __attribute((packed))?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ESP-NOW uses fixed-size data packets (up to 250 bytes). The *__attribute__((packed))* removes compiler-added padding for precise byte alignment.
