PCB Design for Arduino Mega

Worked for 34 sec

Actualizado: la alimentación queda definida como USB hacia el Arduino Mega, y el shield toma 5V/3.3V desde los headers del Mega; VIN queda intencionalmente sin usar.

Archivos actualizados:

Siguiente paso recomendado: pasar al layout del shield y definir la forma/contorno compatible con Arduino Mega.

SPLIT ONE CONECTOR PER MOTOR

Thought for 4 sec

flux

Entendido. Voy a separar el conector actual de motores en dos conectores independientes: uno para motor izquierdo y otro para motor derecho, manteniendo las mismas señales del pinout.

Worked for 2 mins

flux

He separado la interfaz de motores en dos conectores:

J1 = motor izquierdo: PWM, DIR, BRAKE, STOP, HALL_LEFT, GND.
J2 = motor derecho: PWM, DIR, BRAKE, STOP, HALL_RIGHT, GND.

También coloqué J2 junto a J1 en el layout y actualicé la Project Specification. Queda listo para continuar con placement/routing.
