Hola. He leído sobre su proyecto y estoy muy interesado en hacer este proyecto. Disfruto del desarrollo de esquemas y PCB de circuitos electrónicos, también del diseño y creación de modelos 3D y huella de componentes electrónicos (Altium y Eagle). En mi perfil (https://www.freelancer.es/u/nico2747?w=f) puede ver muchos proyectos que realicé relacionados con los archivos de informes de diseño y salida de PCB, usando Eagle, Easyeda, Proteus y Altium. Uno de estos proyectos es el rediseño de un sistema de iluminación inteligente (producto que enciende y enciende la bombilla usando un sensor táctil o una solicitud a través de un servidor web) utilizando Altium designer 18. Primero fue rediseñar el circuito agregando un PIC16F688 y un ESP01 y eliminar un ESP07 y con esto, reducir el número de resistencias del circuito anterior, de 18 a 10, que puede ver en el Sistema de iluminación inteligente en mi perfil. Todos los componentes En el sistema se agregaron el proveedor, la huella, el símbolo y el modelo 3D, y se utilizaron para crear el esquema, PCB, modelo 3D, archivo Gerber y BOM. Estaré encantado de ayudarle con este diseño de PCB y espero escuchar de usted pronto! Saludos cordiales, Ing. Nicolas Moreno.
